Compress PDF: reduce the file size and keep it readable
Job portals, government systems and email services often limit attachment size. When a PDF is over the limit, compressing solves it: the tool reduces the file size while keeping the document readable and faithful to the original.
You control the quality level with a slider. Lower values produce smaller files; higher values preserve more detail in images.

When to use this tool
- Attaching documents to emails with a size limit.
- Submitting resumes, receipts and forms on portals with an upload limit.
- Saving space when archiving large volumes of documents.
- Making it easier to send scanned PDFs, which tend to be very heavy.
Tips for a good result
- Most of a PDF’s weight is in its images. Text-only documents are already light and shrink very little.
- Start at 75% and only go lower if the file is still too large. Below 50%, photos and scans may look visibly worse.
- Check the result full screen before sending, especially in documents with small print.
Frequently asked questions
How much smaller will the PDF get?
It depends on the content. Scanned PDFs or PDFs with many photos shrink a lot; pure-text PDFs shrink little because they are already light.
Does compression hurt the text?
The goal is to keep the text readable. The bigger effect is usually on images, controlled by the quality level.
My file is over 60 MB. What now?
Split the PDF into parts with Split PDF, compress each part and, if needed, merge them back afterwards.
What are the limits of the free plan?
The free plan allows 10 conversions per day, with files up to 60 MB and no sign-up required. The Premium plan removes the daily limit and the ads.
