How do I reduce a PDF's size for an online form?
The site rejects your PDF because it is too large? OUFRID's PDF toolbox compresses it in your browser, without sending the document to a server.
🔒 Free, no sign-up, your files stay on your device.
Step by step
- Open the PDF toolbox, "Compress" tab.
- Choose your PDF.
- Pick the compression level, then start.
- Download the lighter PDF and check its size before sending it.
Good to know
Are my documents sent online?
No, everything happens on your device: ideal for an ID document or a payslip.
Why is my PDF so large?
Usually because of very high-resolution photos or scans. Compression shrinks them.
Can the text still be selected?
Yes with lossless optimisation. With strong or maximum compression, each page becomes an image: the text stays readable but can no longer be selected. Keep the original.
