Compress PDF to 1MB
1 MB is the most common upload limit for scanned contracts, invoices and ID documents. This tool compresses your PDF just enough to fit under it, keeping as much quality as possible — on your device.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop your PDF into the box — the 1 MB target is preset.
- The tool compresses with the gentlest settings that fit the limit.
- Download the result and check the final size next to the file.
Frequently asked questions
My scanned PDF is 8 MB. Will it reach 1 MB?
Almost always, yes. Scans compress very well: most of the size is image data that can be re-encoded much more efficiently while staying perfectly readable.
Is quality better at 1 MB than at smaller targets?
Yes. The tool always uses the gentlest compression that fits the limit — a 1 MB target usually keeps pages looking close to the original, unlike 100 KB.
Will the text remain selectable?
No — guaranteed size targets require rasterizing pages. If keeping selectable text matters more than the exact size, use the Compress PDF tool in smart mode instead.
Is my document uploaded?
No. All compression happens inside your browser; your files never leave your device.
