About Compress PDF To Target Size Online
What this tool does
Compress PDF to a target size shrinks a PDF toward a size you choose, which helps when a form or email only accepts files up to a set limit. Enter the limit, and the tool aims to get as close as possible without going over.
How it works
Your PDF is processed on our server. Images are downsampled and internal data is recompressed in steps until the file fits. Heavier compression can make images look softer.
What to expect
Some files can't reach very small targets, especially when they are mostly text or already compressed. If that happens, you still get the smallest version we could make, and a note tells you the final size.
Limits
The lowest possible target is 10 KB. Password-protected PDFs aren't accepted, so unlock them first.
How to use this tool
How to use
Upload your PDF in the "PDF file" field.
Set the target size and choose MB or KB. This is the largest file size you want.
Press Run and wait for the compression to finish.
Check the note to see the final size, then press Download compressed PDF.
Tips
- Open the result before sending it. Check that images and small text are still clear.
- Use a higher target if the quality drops too much.
- Keep your original. Compression can't restore image detail once it's removed.
