Compress PDF free
Reduce compatible JPEG images and optimize PDF streams locally. Preserve text and vectors and compare actual file sizes.
Unencrypted PDFs without forms, portfolios or digital signatures only. Page copying can lose bookmarks, accessibility tags, attachments and some links. Keep the originals and review the result. This is not a PDF sanitizer.
How to use this tool
Select your files. They remain on your device.
Review the preview and choose the options below it.
Process locally, preview the result and download a new copy.
When to use it
Reduce a photo-heavy report for sharing. Lossless mode optimizes eligible uncompressed streams.
Limits and privacy
Lossy modes optimize compatible RGB JPEG images only; other images remain intact. Text and vectors stay selectable. Quality and colors can change. Reduction depends on the input.
PDF parsing keeps the document in memory. Limits of 25 MB per PDF, 60 MB per batch and 300 pages help bound memory on mobile devices. Rendering is limited to 16 megapixels per page, and exports to 120 MB. Very complex files can still exceed device memory.
Questions and answers
Are my documents uploaded?
No. Processing and preview run in your browser. Reloading or starting again releases the session. Nothing is saved to a user account.

Is the original replaced?
