About compressing PDF
PDF and Word files are usually small on their own — their size comes almost entirely from embedded photos and scanned pages.
Compress a PDF before emailing it (most inboxes cap attachments around 20-25MB) or uploading it to a portal with a size limit.
Typical size reduction
Documents with photos or scans often shrink 30-70%; text-only files barely change — there's nothing left to compress.
Frequently asked questions
How much smaller will my PDF file get?
It depends on what's inside the file. Documents with photos or scans often shrink 30-70%; text-only files barely change — there's nothing left to compress. Preview all three levels before you commit — no guessing.
How do I compress a PDF file?
Upload your PDF file above, pick a compression level, and download the smaller file — all done instantly in your browser.
Will compressing my PDF file reduce quality?
Lighter compression preserves more visual quality; stronger compression trades some quality for a smaller file. Preview the size before you choose.
Can I compress multiple PDF files at once?
Yes. Upload as many PDF files as you want and compress them all together, then download individually or as a zip.
Are my files stored anywhere?
No. Your file is processed just long enough to compress it, then discarded immediately — never stored on disk, logged, or shared with anyone.
Is compressing PDF files free?
Yes. Compressing PDF files on Other Streets is completely free with no limits.
