JPG
Classic .jpg extension, tuned quality search. Best for photographic content and the smallest files overall.
AI image-to-image compressor
Make images
small again
Drop up to 9,999 images, let the analyser read each one, and pull them back down as JPG, JPEG, PNG, APNG or GIF. Enter an exact target size or let it decide. Sizes in and out are detected automatically, files are never re-saved at their original weight, and every result is verified so nothing comes back corrupted.

AI auto-detect
- Samples colour spread, edge energy, transparency and frame count of every image.
- Photos go to JPEG, flat graphics and transparent art to palette-optimised PNG, animations keep their frames in GIF or APNG.
- Strength is tuned per image, then escalated until the file is genuinely smaller.

Output formats
Five ways out. Download any of them per image or as one zip.
JPEG
Identical encoder, .jpeg extension for pipelines and CMSs that insist on the long form.
PNG
Alpha preserved. Palette quantisation shrinks flat art, screenshots and logos far below a plain re-save.
APNG
Animated PNG in, animated PNG out — every frame and delay is kept, with 32-bit transparency intact.
GIF
Full frame-by-frame re-encode with per-frame palettes, transparency and the original loop timing.
WDP
Deliberately removed. No browser can decode or encode JPEG-XR / WDP, so it is not offered as an output — and any .wdp you drop is flagged and cleared with the Delete WDP button instead of being turned into a broken file.
The engine
Four guarantees, one pass per image.
01
Auto-detect on drop
Type, pixel dimensions and exact upload size are read the moment a file lands — nothing to configure, nothing to guess.
02
AI content analysis
Colour spread, edge energy, transparency and frame count are sampled to classify each image as photo, flat graphic, transparent art or animation, then the codec and strength are chosen for it.
03
Size-locked search
Ask for 44.80 MB — or any size — and quality is binary-searched, with resolution stepping down only when the target still cannot be met. The resulting size is detected and reported back.
04
Never bigger, never broken
Output must be smaller than the source or the original bytes are handed back untouched, and every encode is decoded again before it is accepted — so a compressed file is never corrupted.
