Compress PDF to 5MB
Set a 5 MB ceiling and add a PDF file; the page re-encodes it in your browser and keeps stepping quality and dimensions down until the file fits inside 5 MB. Because both are search variables, detail is preserved for as long as the budget allows instead of being thrown away at a fixed setting.
Current limit: up to 50 files · 1024 MB per file. Options vary by format.

Frequently Asked Questions About Documents Compression
Will a 5 MB attachment get through webmail filters?
A 5 MB file plus encoding overhead can push the whole message past a 5 MB cap, so aim nearer 4 MB when the recipient's provider states 5 MB as the limit for the entire email.
Why is the result still not exactly 5 MB?
Encoders trade quality against bytes, so the output lands at or just under the 5 MB target rather than on it to the byte. Tighten or loosen the setting and run again until the size fits.
How much of the 5 MB budget goes to dimensions and how much to quality?
The page tries the largest clean frame that still fits first, then lowers quality only when size alone cannot reach 5 MB. Check the reported output size before you publish.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the PDF file at or under 5 MB.
What should I check before using the result?
Open the PDF file at or under 5 MB in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Will the PDF always be smaller than 5MB?
The tool tries several settings and reports the best available result. Complex or image-heavy PDFs may not reach the target without a substantial quality tradeoff, so inspect the actual output size.
Compress PDF to 5MB
Try to reduce a PDF to 5MB or smaller for a form, email attachment, portal, or upload limit.
How to Use
- Choose a PDF file or drag it into the upload area.
- Enter a password only if the PDF requires one to open.
- Start compression to 5MB; the browser tests several image quality and resolution settings.
- Compare the final size and inspect every page before downloading or submitting it.
Best Use Cases
- Government, school, work, or application forms that accept PDFs up to 5MB.
- Email or document portals with a fixed attachment limit.
- Scanned PDFs where page images account for much of the file size.
Output Format
The download remains a PDF, but this target-size workflow rebuilds pages as compressed images. It aims for 5MB or less and returns the best available result when the target cannot be reached. Selectable text, links, forms, bookmarks, annotations, and accessibility structure may not be preserved.
Privacy
Target-size processing runs in the browser after the PDF libraries load. The document is not sent to a compression API by this workflow. Do not process confidential or third-party files unless you are authorized to do so.
