How to compress PDF to 1 MB
- Add your PDF — up to 20 at a time.
- The target is already 1 MB; change it in the options if your form allows a different size.
- Click Compress and download — the result shows the new size.
How the 1 MB target is reached
The PDF is compressed with up to six progressively stronger settings — from high-quality images up to 2,600 pixels on their longest side, down to 800 pixels with strong JPEG compression — and the first result under 1 MB is kept, so images lose no more detail than they must. Text and vector graphics are never re-encoded, so even at the strongest setting the words stay sharp; only photos and scans get softer.
What if my PDF can't get under 1 MB?
You get the smallest version that keeps text readable, with a note that it didn't reach 1 MB. Splitting the PDF or removing pages you don't need usually closes the gap.
Which PDFs can reach 1 MB?
Most text documents and short scans fit easily. Long, photo-heavy PDFs may need splitting into parts.
Can I choose a different size?
Yes — type any number in Target size (in KB, e.g. 1024 for 1 MB). Leave it at 0 to use a compression level instead.
Are my files safe?
Yes. Your files are only used to create your result — they’re never shared and never used to train AI.
