How to use it
- Choose or drop the PDF you want to make smaller.
- The level is already set to Target size and 500 KB. Change the number only if your form asks for a different limit.
- Press Compress PDF and wait while the pages are processed.
- Check the new size, then press Download compressed PDF.
Where the 500KB limit is used
500 KB is common for multi-page uploads: bank statements, experience letters, project reports and application forms on job, visa and university portals. It is generous enough for several scanned pages at good quality.
Tips for multi-page documents
- Put all pages into one file first with Merge PDF or JPG to PDF.
- Compress the combined file with the target set to 500 KB.
- Scroll through every page of the result before uploading, so no page is unreadable.
If your file is already under 500 KB, you do not need to compress it; most portals accept anything up to the limit.

Frequently asked questions
Will my PDF look good at 500KB?
For most documents, yes. 500 KB leaves room for several scanned pages at good quality, so text, tables and stamps stay sharp when printed.
Should I choose 500KB or Recommended?
If the form gives a 500 KB limit, use the target size so you are sure the file fits. If there is no limit, Recommended gives good quality and usually a much smaller file than the original.
Why is my 500KB PDF blurrier than expected?
Large page counts share the same 500 KB, so each page gets less space. Remove pages the form does not need, or upload the document in parts if that is allowed.
Will the text in my PDF stay selectable?
With Basic, yes: the PDF is only re-packed more efficiently. Recommended, Strong and Target size turn each page into a compressed image, so the text can still be read and printed but can no longer be selected or searched.
Is my PDF uploaded anywhere?
No. The PDF is read and rebuilt in your browser with the open-source pdf.js and pdf-lib libraries, so it never leaves your device.
