Compress PDF to 5MB

Drop your PDF into the box above and press Compress. The tool is already set to a 5MB target, so it automatically applies the lightest compression that gets you under 5MB, then hands you a download link. The whole process happens on your own device.

Most can. Text-heavy documents compress dramatically. Very long scanned documents — say 100+ pages of high-resolution photographs — may not reach 5MB while staying readable. In that case we return the smallest usable version and tell you the target was missed, so you can split the document instead.

We always try the gentlest setting first and only escalate if the file is still too large. For typical business documents at 5MB, text stays perfectly sharp because it remains real vector text — only embedded images are downsampled.

Your PDF was probably already optimized — for instance exported by Acrobat with compression enabled, or generated as pure text with subset fonts. When we cannot beat the original we deliberately return your untouched file rather than a worse one.

It is gone from the page entirely. The document is held only in the tab's volatile memory during processing and is discarded when the tab closes. Nothing is written to browser storage, no cookie records it, and no copy exists anywhere else — your original stays untouched on disk.

Yes. Bookmarks, the table of contents, internal cross-references, hyperlink annotations and interactive form fields all survive compression. Only the encoding of images and content streams is altered — the document's structural and navigational layers are preserved.

Text always stays sharp because it remains real vector text rather than an image. Embedded photographs are downsampled and re-encoded, so quality loss scales with how aggressive a preset you choose. Less Compression is visually near-identical to the original.

Not while it is encrypted. A protected PDF has its content streams encrypted, so the compressor cannot read the images it needs to optimize. Remove the password in your PDF reader first, compress, then re-apply protection to the smaller output if you still need it.

Nothing persists. The compressed result lives in your browser tab's memory until you download it, and everything is discarded the moment you close or refresh the page. There is no server-side copy because the file was never sent anywhere.

Very well, because the file itself is never transmitted. Only the page and the compression engine are downloaded, once, and they are then cached. Uploading a 100 MB PDF to a server-based tool would consume 100 MB of your data allowance; here it consumes none.
