Reduce your PDF's file size
Upload portals, email and job/exam forms often cap PDF size. This free compressor re-encodes your PDF's pages to make the file smaller — pick a compression level or a target KB — entirely in your browser, so the document never leaves your device. It's most effective on scanned or image-heavy PDFs.
Who uses this tool
Students uploading to government portals capped at 1–2 MB, professionals emailing large scanned documents, job applicants whose scanned CV or certificates exceed a job portal's size limit.
How to compress a PDF
- Choose your PDF.
- Pick a compression level (Strong/Medium/Light) or switch to Target size and enter the KB you need.
- Click Compress, check the new size, and download.
Frequently asked questions
How do I reduce the size of a PDF?
Choose your PDF, pick a compression level (or a target KB), and click Compress — then download the smaller file.
How do I compress a PDF to 100 KB or 200 KB?
Switch to "Target size", enter the KB, and compress. For very small targets on long PDFs, the tool saves the smallest version it can reach.
Does compressing remove the text?
To shrink the file, pages are saved as images, so text becomes non-selectable. This works best for scanned/image PDFs; text-only PDFs are usually already small.
My PDF is password-protected — can I use it?
Yes. Add it like any other PDF and ToolGalli will ask for the password right here, then carry on. The password is used in your browser and never sent anywhere.
Is my PDF uploaded anywhere?
No. It's compressed entirely in your browser and never sent to a server.
