Compress a PDF to 300 KB
300 KB is a common middle-ground cap on application, university and employer portals. This page opens our Compress PDF tool with 300 KB ready as the target: a lossless save is tried first, and only if the file is still too big does the tool reduce page clarity in steps, keeping the clearest result that fits under your cap. You see the original size, the final size, and whether the target was met, before you upload anywhere.
How to do it
- Add your PDF file.
- Confirm the target shows 300 KB.
- Click Compress PDF and download the file that fits.
Common questions
Is 300 KB enough for a multi-page document?
Usually yes for text documents and modest scans. Long photo-heavy files may need the stepped shrink and will still stay readable at this size.
Will my text stay selectable?
Yes if the lossless save reaches the target. If the stepped shrink is needed, pages become clear pictures and the result panel explains it.
Are my files uploaded?
No. Everything runs on your device.
