Compress PDF to 1 MB
One megabyte is the default ceiling here. Pages are still converted to pictures so the file can shrink.
- No upload
- No watermark
- No login
Pages become pictures, so text will not stay selectable. If the limit would make the page unreadable, you get an error instead of a bad file.
Your files never leave this device. There is no account and no watermark on the download.
1 MB means 1024 KB on this chip
The button is labelled 1 MB and sends 1024 as the KB field so the decimal ceiling is about one million bytes. You can type 1000 if a portal is strict about decimal megabytes.
When not to compress
If the PDF is already under 1 MB, you do not need this. Recompressing a text PDF into images can make it larger and less useful.
FAQ
How do I compress a PDF to 1MB?
Choose the file and press Compress. Download after you look at the first-page preview.
Does this upload the document?
No. pdf.js and the new PDF are loaded and built in the browser, and only after you choose a file.
What if it is still too big?
Remove pages or raise the limit. The tool will not cross its quality floor to force 1 MB.
