AI SearchSmart compression, not blind compression
Most tools rasterize your whole PDF. We only touch what's oversized.
Pick your PDF
Drag & drop or choose a file. It opens instantly in your browser. Nothing is uploaded anywhere.
Images get right-sized
The engine measures how large each image is actually displayed, downscales oversized ones and re-encodes them efficiently, transparency included.
Download
Your PDF is rewritten with clean, deduplicated objects. Text and vectors stay untouched and razor sharp.
Private by design. Free by choice.
100% private
Compression runs in your browser via WebAssembly. Files are never uploaded, stored or logged.
Text stays sharp
Only images are recompressed. Fonts and vector graphics are left untouched and selectable.
No watermarks, no limits
No signup, no page limits, no upsell walls. Files up to 500 MB.
Display-size aware
Images are downscaled to the size they're actually shown at. That is the safest way to shrink without visible loss.
Transparency-safe
Alpha masks are preserved and compressed too, so logos and cutouts keep their clean edges.
Fast, even offline
A 150 MB design deck compresses in seconds on a laptop. Once loaded, it even works offline.
Are my files uploaded to a server?
No. The entire compression runs inside your browser using WebAssembly. Your PDF never leaves your device. Nothing is uploaded, stored or logged.
Is it really free?
Yes, completely free, with no signup, no watermarks and no page limits. It's a free tool built by Moneo, a software & product development company.
How much smaller will my PDF get?
It depends on the file. PDFs exported from design tools (Figma, Sketch, Canva) with large lossless images often shrink by 80-95%. Files whose images are already efficiently compressed will shrink less.
Will text stay sharp and selectable?
Yes. Only images are recompressed. Text, fonts and vector graphics are left untouched, so they stay razor sharp and fully selectable at any zoom level.
Is there a file size limit?
Files up to 500 MB are supported. Because processing happens on your device, very large files simply take a little longer depending on your hardware.
How does the compression work?
The engine measures the size at which every image is actually displayed on the page, downscales oversized images to what is really needed, converts them to efficient JPEG encoding (transparency masks included), removes duplicates and rewrites the PDF with garbage collection.
