Compress PDF to 100KB, 200KB, 500KB or 1MB Free
Shrink a PDF to an exact size — 100KB, 200KB, 500KB, or 1MB — for email attachments, web forms, and online applications. Free, no signup, runs in your browser.
Some situations do not care how good your PDF looks — they care about the number on the file size label. An email server rejects anything over its attachment cap, a government portal caps uploads at 1MB, a job application form wants a resume under 500KB. This tool lets you type in the exact ceiling and get a PDF at or under it, instead of guessing which quality slider gets you there.
Pick a preset — 100KB, 200KB, 500KB, or 1MB — or enter any custom value down to 10KB, and the compressor works backward from that number. It downsamples and re-encodes embedded images, iterating automatically until the output fits your target or it runs out of room to shrink further. Everything happens in your browser; the file is never uploaded to a server.
How it works
Upload your PDF
Drop in the file you need to shrink. Works with scanned documents, image-heavy reports, and standard text PDFs up to 500MB.
Pick a target size
Choose 100KB, 200KB, 500KB, or 1MB, or type a custom size. The compressor automatically re-encodes images to land at or under that number.
Download the result
Get your resized PDF in seconds. If the exact target isn't reachable, you'll see the closest size it could achieve and why.
Common use cases
Email attachments under 100KB or 200KB
Many mail servers and webmail clients silently strip or bounce large attachments. Compressing a scanned form or signed contract to 100KB or 200KB keeps it well inside typical limits.
Government and application portals near 500KB
Visa applications, tax portals, and job application systems often cap document uploads at 500KB. Hit that ceiling reliably instead of resubmitting a rejected upload.
Web forms and CMS uploads capped at 1MB
Contact forms, university admissions systems, and content management tools frequently enforce a 1MB file limit. Compress your PDF once instead of trimming pages to fit.
