GIF Editor FAQ
Is my file uploaded, or does editing happen locally?
+
Editing happens in your browser; the file goes to our workers only for the operations that genuinely need server-side processing, and it is deleted shortly afterwards.
What can I actually change?
+
Crop, rotate, flip, resize, draw, add text and shapes, and apply filters and colour adjustments. Everything is applied to a working copy, so the file you uploaded is never modified in place.
Does the file format limit what the editor can do?
+
It does. GIF is capped at a 256-colour palette with single-bit (on/off) transparency and no partial alpha, which is why photographs band and dither in it. What the format can represent bounds what any editor can preserve, here or on the desktop.
Anything specific to GIF in the editor?
+
Yes — the palette is shared across the whole animation, so any change to one frame is negotiated against the colours every other frame needs. Worth knowing before you export over your only copy.
Will GIF Editor lower the quality of my GIF animations?
+
The binding constraint on a GIF is not the operation, it is the 256-colour palette. Anything that changes pixel values forces a re-quantisation against a palette shared by every frame, which is where banding and dithering come from. Frame timing and loop count are preserved.
Can I run GIF Editor on several GIF animations at once?
+
Yes, and it is worth doing — per-file overhead on an animation is dominated by decoding every frame, so a batch amortises far better than the equivalent set of single runs.
Is animation preserved, or do I get a still?
+
Animation is preserved. Every frame is decoded, processed and re-assembled with the original delays and loop count intact. You only get a still if you explicitly ask for a single frame.
Does GIF Editor cost anything?
+
No. GIF Editor is free, needs no account, and adds no watermark to the output. Uploaded animations are deleted from the workers a short time after the job completes.
Why does a WebM site host GIF Editor?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running GIF Editor on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once GIF Editor is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is GIF Editor here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploaded video is deleted from the workers shortly after the job finishes, nothing is watched and nothing is indexed. Free accounts exist for history and batch size, not for access.
