How to use Fit PDF to a Target Size
Add your PDF. Drop one PDF onto the upload area or choose it from your device.
Check the mode. Fit to a target size is already selected. Switch to Compression level if you would rather pick Low, Medium or High.
Type the target. Enter the size in Target size (MB). The smallest value accepted is 0.1.
Fit the PDF. Select Fit PDF to size and wait for the progress bar to finish.
Download the result. Compare the original and new sizes, then download the file. If the target was missed you are told.

- The tool tries up to 6 quality levels. If the target cannot be reached it returns the smallest result it found and says the target was missed.
- A PDF that is mostly text or vector artwork may barely shrink, because there are few images to re-encode.

- Without an account you get 3 free actions on this tool every 24 hours; signing in removes the cap.
Frequently asked questions
How do I make a PDF smaller than a specific size?
Enter the size in MB in the Target size field and select Fit PDF to size. The tool searches for the highest image quality that still fits, and tells you if it could not reach the target.
What if the PDF is still bigger than my target?
You get the smallest version the tool could make, clearly marked as missing the target. A PDF with few embedded photos has little to shrink, so a lower target may not be reachable.
Does fitting a PDF to a size lower its quality?
Only the embedded photos change. They are re-encoded as JPEG at the highest quality that still fits, while text and vector artwork keep their original quality.
Is my PDF uploaded?
No. The compression runs in your browser, so the file stays on your device.
