What this opens on
The GIF studio at 2× with square pixels. The original plays on the left; the enlarged one plays beside it as soon as it is built, so you can compare the motion before downloading.
| Factor | Each frame | All frames together |
|---|---|---|
| 2× | 400 × 400 px | 1.9 megapixels |
| 4× | 800 × 800 px | 7.7 megapixels |
| 8× | 1,600 × 1,600 px | 30.7 megapixels |
One recipe for every frame, the original timing and loop, and a read-back that proves both.
Where this falls down
- GIF files get big.Four times the pixels at 2× is roughly four times the file, and every frame is stored whole. Smooth GIFs grow faster than square-pixel ones.
- Smooth GIFs stay limited to 256 colours a frame.That is the GIF format, not this page: soft gradients can show steps after a Lanczos enlargement.
- Animated WebP and APNG are not read here.This page reads GIF. Other animated formats open as their first frame in the main enlarger.
Questions people ask
Does the animation keep its speed?
Yes. Each frame keeps its own delay and the GIF keeps its loop count. After saving, the page reads the new GIF back and confirms the frame count, every delay and the loop.
Square pixels or smooth?
Square pixels (nearest neighbour) suit pixel art, emoji and screen recordings, and keep every colour exactly — the read-back confirms no new colours. Smooth (Lanczos) suits photographic GIFs; the in-between colours it makes are mapped back onto each frame's own colours, because a GIF frame can hold only 256.
Can I use the AI models on a GIF?
No. The trained models run on still pictures only; enlarging dozens of frames with one, each guessing its own detail, would make the detail flicker from frame to frame. GIFs use the two arithmetic methods.
Why is a big factor greyed out?
Every frame is counted. A 200 × 200 GIF with 12 frames at 8× is 1,600 × 1,600 × 12 — about 31 million pixels. The page offers the largest factor whose frames together stay under this device's ceiling (80 megapixels on a computer, 24 on a phone).
Is my GIF uploaded?
No. The GIF reader and writer run in this tab; the frames are enlarged here and the new file is made here.
Better fit?
- Pixel art upscaler Whole-number scaling only: every pixel a square block, no new colours, checked in the saved PNG.
- Enlarge a PNG Transparency-first: premultiplied resampling with no dark fringe, edge-guided for logos, PNG or WebP out.
- Double the size The factor with the least to apologise for. Opens at 2× on a sharp source.
- Bulk enlarge images One recipe, many files, one at a time, into one ZIP with a record of each.
