The two modes for GIF
Smaller files (lossy)
"Smaller files" recompresses the GIF; it stays animated. GIF's 256-colour palette limits how much can be saved.
Exact quality (lossless)
"Exact quality" recompresses the GIF losslessly; frames and timing are identical.
How to compress GIF files in ConvertX
- 1
Open Image Compressor
On the Home screen tap Image Compressor.
- 2
Select your GIF files
Tap "Select image files" and pick the GIF images. On desktop you can drag them in.
- 3
Pick a mode
Choose "Smaller files" (lossy, with the Light, Balanced, Strong or Maximum preset, or a custom quality) or "Exact quality" (lossless where the format allows).
- 4
Check the estimate
The app estimates the result size on one file before you run the batch, so you can adjust the preset first.
- 5
Optional: maximum width
Set a maximum width to resize large images; smaller images are left as they are.
- 6
Start and collect
Tap "Compress N images". The Queue runs the batch; the summary shows the total saved and View Library opens the results.
Tips
- For a big saving, convert the GIF to animated WebP instead: 60–90 % smaller is common.
- A maximum width shrinks oversized GIFs more than any recompression.
Nothing is uploaded
Compression runs on the device; originals are never modified. Location and camera details are removed unless you turn on "Keep photo details". See the guide to compressing without losing quality for how the presets compare.
Frequently asked questions
Does compressing a GIF keep the animation?
Yes, in both modes.
Why is the saving small?
GIF's LZW compression and 256-colour limit leave little room. Convert to WebP for real savings.
