Compress PDF

Make a PDF smaller — or bring it under a size like 100 KB for a form. Free, no signup; text stays sharp.

Drop your PDF here or choose a file

.pdf only, up to 50 MB

Leave empty to just make it smaller. Text always stays sharp.

Note: at very small sizes (like 10–20 KB) a scanned page is saved in black and white, so a red stamp or blue signature turns black. To keep colours, choose a bigger size such as 100 KB.

Your file is deleted from our server right after compressing.

Your file stays private. It is sent over an encrypted (HTTPS) connection, used only to make your result, and deleted as soon as you're done. Never shared, never sold, never looked at. Privacy policy

Compression shrinks a PDF by downsampling and re-encoding oversized images inside it. Text, fonts and vector graphics are left untouched, so the document stays sharp and searchable.

Frequently asked questions

Yes. Type the size under Compress to and pick KB or MB. The PDF comes out just under that size. If a PDF is mostly text and can't get that small, you get the smallest possible version and are told its size.

To reach a very small size like 10 or 20 KB, a scanned page of text is saved in black and white, the way a fax is. Letters stay sharp and readable at a fraction of the size, where a colour version would turn blurry. Set a bigger size, such as 100 KB, to keep the colours.

No. Only raster images are compressed - text and vector content are copied over untouched, so they stay sharp at any zoom level.

It depends on what is inside. Image-heavy scans often shrink by 90% or more, while a text-only PDF may barely change - in that case we return your original file rather than a larger one.
