Screen capture software can save still images and screen recordings in several formats, but those format lists describe different kinds of output. To choose well, check which formats are editable working files, which are export targets, what operating systems the software supports, and whether video conversion needs separate configuration.
Snagit and ShareX offer different workflows rather than interchangeable format lists. Snagit supports Windows and macOS and combines capture, annotation and sharing; ShareX is Windows software with configurable capture tools and a video converter that needs FFmpeg set up.
Image capture formats and recording formats are different
A screenshot is a still image. PNG, JPG, BMP, GIF and TIFF are examples of image formats, but they do not all behave alike. PNG is often useful for interface captures where text and sharp edges matter; JPG is commonly used when a smaller file is more important and some compression artefacts are acceptable. The right choice depends on what you will do with the image, not on which format appears first in a list.
A screen recording is moving video, normally saved in a container such as MP4, WebM, MKV or AVI. A container packages streams such as video and audio; the codec determines how those streams are encoded. Thus “MP4” alone does not tell you everything about quality, compatibility or file size. An animated image format such as GIF, WebP or APNG can also represent a sequence of frames, but it is not simply another name for a conventional video recording.
The intended use changes the useful format. A screenshot for a training note may need crisp labels and later annotation. A short motion demonstration might be easiest to share as a video, while a looping animation can be suitable for a small, silent example. For an always-on YouTube channel, a screenshot application is not the same thing as a streaming setup: capture and conversion produce files, while a live channel needs an appropriate video source and broadcast workflow. If you are checking a stream privately before going live, see the guide to using a YouTube stream key for a private meditation test.
Before comparing applications, write down the deliverable you need. “An image for a manual”, “a clip to send to a colleague” and “a recording to edit later” imply different requirements. Also note where it must open: in an image editor, a browser, a presentation, a video editor or a platform upload form. Compatibility at the receiving end can matter more than the number of extensions in a product list.
Native files, exports and conversion
A native or project file is intended to preserve information that helps you continue working. It may retain annotations, editable objects, capture metadata or a project structure, depending on the application. An exported file is made for a destination or exchange: it may be flattened, converted, or limited to what the destination can display. The word “format” does not tell you which role a file plays.
This distinction is especially important when a vendor publishes a long list. It may combine source files, common image outputs, a video format, web or document formats, and formats that are available only when exporting. TechSmith, for example, identifies PDF, CUR and EPS as export-only in its Snagit format information. That does not mean a capture opens as an editable PDF project, nor that every extension in its list offers equivalent editing functions. Check TechSmith’s Snagit product information and the current documentation for the release you intend to use.
A practical test is to imagine a change after capture. Can you reopen the project and move a callout, crop or annotation independently? Or can you only modify a flattened image in another editor? If editability matters, look specifically for documentation about the working file and the features it preserves. Do not infer editability from a format’s presence in an export menu.
Conversion adds another step. Changing a file’s extension by renaming it does not convert its contents. A proper converter decodes the source and writes a new file using a suitable codec or image encoding. Conversion can also discard features: transparency, animation, layers, audio tracks or metadata may not survive every target format. Keep the original when the output is important or difficult to reproduce.
Snagit formats and platforms
TechSmith documents Snagit for Windows and macOS. Its listed formats span several purposes: image formats such as BMP, GIF, ICO, JPG, PNG, TIF, PSD, TGA, RAS and WPG; MP4 video; MHT; the Snagit-specific SNAG format; and formats associated with tools or interchange such as EMF, WMF and WFX. The same list includes PDF, CUR and EPS as export-only. Treat this as a mixed capability list, not a promise that each entry is an editable capture project.
For a still-image workflow, the useful question is what you need to hand over. A PNG may suit a clear annotated screenshot; a JPG may suit a photographic capture where reduced size is useful. If someone else needs to revise your annotations, investigate the Snagit working-file behaviour rather than assuming an exported image will retain those objects. A document or web-oriented output can be useful for sharing or archiving, but it serves a different role from a source capture.
Snagit also covers MP4 recording, so it may suit a person who wants to capture a short on-screen explanation alongside their screenshot work. That does not make its image formats video formats, or its exported document formats recording outputs. Confirm current support and any workflow details on TechSmith’s official page before standardising a team’s process, since vendor lists can change between releases.
Platform support can settle the choice before format details do. If you work across Windows and macOS, Snagit’s documented availability covers both systems; check the specific version and any feature differences relevant to your devices. If a team has mixed computers, test the handoff file on the actual receiving machine. A format being supported by an application does not guarantee that every collaborator has an app that can edit it.
ShareX format and platform considerations
ShareX is a free, open-source Windows application, according to its project materials. Its documented workflow includes screenshot capture, recording, annotation, saving, upload actions and utilities. It is not documented as a macOS alternative, so a Mac user should not choose it on the assumption that the same application is available there. Consult the ShareX project page for current platform information.
Its video converter documentation describes several output combinations: H.264 or H.265 as MP4, VP8 or VP9 as WebM, AV1 as MKV, MPEG-4 as AVI, and animated output as GIF, WebP or APNG. These pairings illustrate why a format list needs context. MP4 and MKV are containers; H.264, H.265 and AV1 are codecs. ShareX’s documentation is describing conversion choices, not saying all outputs are identical in compatibility or suited to the same job. The ShareX video converter guide is the primary reference for its current options.
ShareX may fit a Windows user who values configurable capture actions, hotkeys, annotation, upload choices and utilities in one workflow. That breadth comes with choices to make: decide where captures are saved, what happens after capture, and whether an upload action is appropriate for the material. For sensitive internal screens, local saving may be preferable to an automated upload destination. Review the action and destination settings rather than assuming “capture” always means “save locally”.
The format options do not remove the need to test outputs. An animated file can be convenient for a short visual instruction, but it may be a poor fit for detailed audio or longer demonstrations. A conventional video file is often more appropriate when sound, duration or later video editing matters. The software’s supported option is only one part of the choice; the recipient’s player or editor must also handle it.
Check whether conversion needs configuration
ShareX conversion requires a configured FFmpeg executable. In practice, that means checking the converter setup before relying on a particular output. A menu entry for a codec does not prove that the necessary encoder is available in the FFmpeg build on your machine. ShareX’s documentation also notes that encoder availability can depend on the build, hardware and drivers.
Use a short, non-critical test capture. Configure the executable as described in the current ShareX guide, choose the intended container and codec, convert a small file, then open the result in the application or player that will receive it. Check picture, sound if present, timing and whether the file can be edited as planned. This catches setup problems before a longer recording or a deadline.
Do not treat an error as evidence that every format in the documentation is broken. First check whether FFmpeg is configured, whether the selected encoder is present, and whether the installed build and hardware support that path. If a hardware encoder is unavailable, a software encoder may be another documented choice, though encoding behaviour and speed can vary. No universal performance conclusion follows from a format list.
Conversion is also worth testing when you move between image and animation workflows. Verify transparency and frame timing if they matter, and compare the output with the original. When the file will become part of a recurring process, record the selected output settings and where the converter executable is configured. That makes it easier to diagnose a future change after an application or FFmpeg update.
Choose by workflow and output needs
Start from the job, then narrow by platform and file role. If you need editable annotations and a cross-platform capture workflow, examine Snagit’s working-file and export behaviour on the operating systems you use. If you are on Windows and want a configurable, free and open-source capture tool with multiple conversion targets, ShareX is worth evaluating, provided you are comfortable configuring and testing FFmpeg. Neither description is a performance ranking.
| Need | What to check | Likely fit to investigate |
|---|---|---|
| Still screenshots with annotation and sharing | Which elements remain editable in the working file; what exports are available | Snagit’s documented capture and annotation workflow |
| Windows capture with configurable actions | Hotkeys, after-capture behaviour, save location and upload destinations | ShareX’s Windows workflow |
| Screen recording for a common video handoff | Container and codec, audio needs, recipient player or editor | Snagit MP4 recording or ShareX conversion options, tested for the destination |
| Animated visual example | Whether GIF, WebP or APNG is supported and whether animation is preserved | ShareX’s documented animated conversion choices |
| Mixed Windows and Mac team | Supported platforms and which file can be opened by each recipient | Snagit is documented for both; confirm release details |
| Long-term editable source | Native/project format and what it preserves | Verify application-specific working-file documentation before choosing |
For example, a small business preparing a troubleshooting guide might capture a settings screen, add arrows, retain an editable source and export a clean image for staff. A study channel operator making a brief silent demonstration might instead need an animated output. A screen-recorded explanation with narration calls for a video workflow and an audio check. These are separate deliverables, so buying or installing software solely because its format list looks long can leave the real requirement unmet.
If the final goal is a 24/7 YouTube channel rather than a one-off recording, keep the capture decision in its place. The artwork or screen recording you create is an input asset; it is not itself a continuously managed live broadcast. For a channel built around a prepared video file, the cloud streaming workflow guide explains a separate operational question. If your channel loops multiple assets, consider how you will update a playlist while a 24/7 stream is running. For a screen recording intended as a stream source, YouTube’s live encoder settings guidance is the official place to check current broadcast requirements; it does not replace choosing the right capture format.

FAQ
What formats can screenshot software save in?
It depends on the application and the intended output. Common still-image choices include PNG and JPG, while some tools also list formats for project files, documents or other workflows. Check whether each listed format is an editable working file or an export target.
Can screen capture software save recordings as MP4 or GIF?
Some tools support MP4 video, and some offer animated formats such as GIF, WebP or APNG. They are not equivalent: choose based on sound, duration, animation and where the file must play. Confirm the exact converter setup and output support in the software documentation.
Which option works on macOS?
TechSmith documents Snagit for Windows and macOS. ShareX describes itself as Windows software, so do not assume it supports macOS. Check official product information for the version you plan to use.
Does ShareX convert video without setup?
Its video converter requires a configured FFmpeg executable, and encoder availability can vary with the FFmpeg build, drivers and hardware. Configure it and test a short recording in the destination player before depending on a conversion workflow.
