Getting a PDF under 1 MB
1 MB is a common cap for supporting documents on government, banking and insurance websites.
How small a PDF can get depends mostly on how many scanned pages it has. A one- or two-page scan usually fits 1 MB with clear text. If a long document won’t fit, upload the pages that matter most, or split it into separate files if the form allows several uploads.
Portals don’t all count kilobytes the same way, so we aim a little below 1 MB. Check the size shown after compression before you upload.
How it keeps your text sharp
Most of a PDF’s size comes from the pictures inside it, like scanned pages and photos. We look at each one and pick the right treatment, then rebuild the PDF to land just under your limit.
Scans stay crisp
Letters, forms and IDs are turned into clean, flat ink colours, so small print stays legible.
Photos stay natural
Photographs are saved as JPEG at the best quality that still fits the limit.
Nothing is uploaded
The work happens in your browser tab, so it’s private and works on slow connections too.

Questions
How do I reduce a PDF to 1 MB?
Choose your PDF above; the target is already set to 1 MB. Press Compress PDF, check the preview, and download. It takes a few seconds for most files.
Is it safe to compress confidential PDFs here?
Yes. Compression runs inside your web browser, so the PDF is never uploaded to us or anyone else. If your browser can't handle a file, you can choose to process it on our server; that's optional, and the file and result are deleted within 1 hour.
Will the text in my scanned document stay readable?
Yes. Pages that look like scanned text are turned into sharp, flat colours instead of being blurred like a photo, so small print and signatures stay crisp. You can compare the result with the original before downloading.
What if my PDF can't reach the size I need?
Long scans at high resolution sometimes can't get that small without becoming unreadable. You'll get the smallest readable version and see how close it came. Rescanning at a lower resolution or splitting the PDF usually solves it.
Is there a file size limit?
In your browser you can compress PDFs up to 100 MB. The optional server option accepts files up to 20 MB.
Does it cost anything or add a watermark?
No. Compress PDF is free, needs no account and never adds a watermark.
