Tips for a PDF under 1MB
- Several pages fit comfortably at this size while staying sharp.
- Long documents get less space per page, so split very long PDFs if they look soft.
- If the PDF is already under the limit, there's no need to compress it.

Compressing a photo instead? Use compress image to KB.
Frequently asked questions
Will the PDF be under 1MB?
Yes, unless the document has too many pages for that size. In that case the tool tells you, and you can remove pages or pick a larger target. It counts 1KB as 1000 bytes, so the file passes whichever way a site measures.
Will I still be able to select or search the text?
No. To reach small sizes, each page is saved as a compressed image, so the text becomes part of the picture. It stays readable, but it can't be selected, copied or searched. Keep your original if you need that.
Is my PDF uploaded anywhere?
No. The whole process runs in your browser, and your file never leaves your device. That makes it safe for ID documents and certificates.
Does it work with password-protected PDFs?
No. Remove the password in your PDF app first, then compress the unlocked copy.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
