Why one web page beats six apps
GIF makers have historically been sold per platform: a paid Mac app, a Windows utility with a bundled toolbar in its installer, an Android app that stamps a logo on every export. That made sense when encoding video needed native code. It does not anymore. Current browsers ship hardware-backed video decoders and fast JavaScript engines, so a page can decode a clip, quantize it to 256 colors per frame, and write a GIF entirely on the device.
Practically, that means the same tool, the same controls, and the same output on every machine you use. Start an edit on a desktop, save the project file, and finish it on a laptop. On a managed work or school device it also sidesteps the usual blocker: there is no installer to approve, no extension to allow, and no admin prompt. If the browser can open a web page, the converter runs.
Windows: record with what is already there
Edge, Chrome, and Firefox all run the converter identically. For capture, Windows already has two recorders most people forget: Game Bar (Win plus G) records any app window, and the Snipping Tool on Windows 11 records a region you draw. Both save MP4s that open here directly. Legacy Windows files are the one thing to watch: WMV and some AVI codecs are not decoded by browsers, and the video formats page has the quick fix.
Mac: Retina is why your GIF came out enormous
Command-Shift-5 records the screen to a .mov, and Safari opens it natively, HEVC included. The trap is pixel density. A Retina capture is twice as wide and twice as tall as what you saw on screen, so a modest window becomes a 2,800-pixel-wide GIF. Downscale to around 800 pixels wide, hold 12 to 15 fps, and trim the palette; interface footage barely changes visually while the file drops by an order of magnitude. Safari, Chrome, Firefox, and Edge all produce the same result.
Linux: keep ffmpeg, use this for the feedback loop
There is no .deb, Flatpak, or Snap to choose between, and Wayland versus X11 does not matter, because the browser owns the display. On Linux the honest comparison is ffmpeg, which remains the right tool for batches, scripts, headless boxes, and unusual codecs. What a page adds is seeing the size estimate and the loop point while you adjust, instead of rendering, checking, and rendering again. One caveat: some distributions build Firefox without H.264 support, so if an MP4 goes black there, Chromium usually opens it.
Chromebook: the school laptop case
ChromeOS is where installable GIF tools are thinnest, and a web page needs no Play Store, Linux container, or extension. The built-in screen recorder in Quick Settings captures the full screen, a window, or a region and saves to Downloads; drop that file in. A 4 GB Chromebook handles a trimmed clip of a few seconds comfortably. Trim first, then downscale to 480 to 640 pixels wide, because a long 4K import is what makes modest hardware struggle. If a managed device blocks the site, that is the school policy speaking, and the teacher is the right person to ask.
iPad and Android: the phone-sized version
On an iPad, Safari runs the full editor. Control Center screen recordings import as .mov with no re-export, and HEIC photos work as five-second freeze-frame clips because Safari decodes HEIC natively. Two differences from a desktop: the Record a Tab button hides itself because iPadOS does not offer the capture API it needs, and memory, not the file cap, is the real ceiling, so trim 4K footage short before export.
On Android, Chrome opens clips straight from the gallery and the touch timeline handles trimming. Most HEVC recordings decode; for the odd one that does not, switching the camera to its most-compatible (H.264) setting fixes it at the source. Phone clips are large in pixels, so bring the long edge to 480 to 600 pixels before anything else. For iPhone specifics, including Live Photos and vertical video, the iPhone page goes deeper.
What is identical everywhere
| Desktop (Windows, Mac, Linux, ChromeOS) | iPad and Android | |
|---|---|---|
| Install | None, it is a web page | None, it is a web page |
| Upload | None, processing stays on the device | None, processing stays on the device |
| Record a Tab | Yes, on browsers with the capture API | Not available, record with the system recorder |
| Exports | GIF, APNG, silent MP4, Frames zip | GIF, APNG, silent MP4 where the browser can encode it, Frames zip |
| Watermark or account | Neither | Neither |
The part that never changes is where the video goes, which is nowhere. Every device does its own decoding and encoding, so a work recording on a corporate laptop and a family clip on a tablet are handled the same way: read from local storage, rebuilt as a GIF, saved back to local storage. The no-upload page explains how that is enforced rather than promised.
