How to compress a PDF to 1 MB
Upload forms, job portals and government sites often set a maximum file size, and 1 MB is one of the limits people run into. That is a comfortable limit for most documents. Pages that are mostly text usually stay sharp, and only photo-heavy scans of many pages need a lower quality. Set the slider to 1 MB to keep as much quality as the limit allows.
- Drop your PDF on the red sheet, or tap it to choose a file.
- The slider jumps to about 1 MB. Nudge it if you want more quality or a smaller file.
- Press Compress, check the real size, and download the file.
How much space does each page get?
The 1 MB is shared by the whole document, so more pages means less room per page:
| Pages | About per page |
|---|---|
| 1 | 1 MB |
| 2 | 500 KB |
| 5 | 200 KB |
| 10 | 100 KB |
| 20 | 50 KB |
Is my PDF uploaded to a server?
No. The document is processed inside your browser and is never sent to any server. Close the page and nothing is left behind.
Will the result be exactly 1 MB?
We aim for 1 MB, counting 1 KB as 1,000 bytes (slightly stricter than the 1,024 some systems use). The slider shows an estimate; in our tests the real file usually came out a little under it, and you see the real size before you download. If it lands over, lower the slider a bit and compress again.
Why can’t I select the text afterwards?
To make the file smaller, the pages are turned into JPEG images. The text stays readable to the eye but can no longer be copied or searched. If you need to keep selectable text, use a compressor that only recompresses the images instead.
