Compress PDF
Shrink a PDF that’s too big to email or upload — right in your browser, with nothing sent to a server. Keep text crisp and selectable, or recompress scans hard for the smallest possible file.
How to compress pdf
Drop your PDF onto the box above (or click to choose it).
Fudobe opens it in Convert mode.
In the “Compress PDF” section, pick Lossless (keeps selectable text) or a recompress level for scans.
Compress and save the smaller file to your device — nothing was uploaded.
Most online PDF tools upload your file to their servers. Fudobe does it in your browser — your document never leaves your device.
Other compressors shrink your file by first uploading the whole thing. Make it make sense.
compress PDF — your questions
How much smaller will my PDF get?+
It depends what’s inside. Scanned or image-heavy PDFs shrink a lot with the recompress levels; an already-optimized PDF may barely change. Fudobe shows you the real before/after size instead of pretending — if it can’t shrink, it tells you.
Will compressing ruin the quality or the text?+
Lossless mode keeps everything, including selectable text, and just strips structural bloat. The recompress levels turn pages into downsampled images — smaller, but the text becomes a picture — which is ideal for scans. You choose which.
Is my PDF uploaded to compress it?+
No. Compression runs entirely in your browser; the file never leaves your device, unlike upload-based compressors.
Is it free?+
Yes — free, no account, no watermark, because it runs on your own machine.
