Use this page to bring a PDF down under 1 MB without choosing a compression level yourself. The target is already filled in. You add one file, and the tool searches for the highest JPEG quality that keeps its embedded images within budget. Nothing is sent to a server; the work stays in your browser.
When you need a file under 1 MB
- A bundle of scanned pages or photographed receipts has been combined into one PDF, and an upload form or mail client will not take it at full size.
- You are sending a presentation exported to PDF, full of screenshots and pictures, and the recipient's inbox has a modest attachment limit.
- A document is headed for a form that accepts a megabyte or less, and you would rather aim at the ceiling than guess at a preset level.
- A longer scan of a signed agreement needs to stay legible while still getting small enough to attach alongside other files.
What to expect
- One megabyte gives more room than the smaller targets, so a typical scan of several pages often fits with moderate quality loss rather than heavy loss.
- The tool only touches embedded JPEG pictures. If your PDF is large because of fonts, vector art, or non-JPEG images, this mode may not reduce it much.
- Because the search keeps the best quality that fits, a file only slightly above 1 MB usually comes out looking close to the original.
- When the target cannot be met, the output is the lightest one the tool produced, and the result panel says the goal was missed.
How to use Compress PDF to 1 MB
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.
Check the target. 1 MB (1 MB) is already entered in Target size. Change it if you need a different size. The smallest value accepted is 0.1 MB.
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.
Limits and privacy
- One PDF at a time, up to 50 MB.
- Only embedded JPEG images are re-compressed. Text, vector graphics and page layout are left untouched.
- 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.
- The file is processed in your browser and is not uploaded.
- Without an account you get 3 free actions on this tool every 24 hours; signing in removes the cap.
Frequently asked questions
What if my file is still bigger than 1 MB?
You will see that the target was missed, together with the smallest file the tool could make. This tends to happen with documents whose size comes from something other than JPEG pictures. Removing unneeded pages first, or splitting the file, gives the compressor less to carry.
Does this lower the resolution of my images?
It changes the JPEG quality setting, not the pixel dimensions of the pictures. The images keep their size on the page but carry less fine detail.
Are my pages reordered or cropped?
No, the page count, order and layout stay exactly as they were. Only the data of eligible embedded pictures is rewritten, so the document reads the same as before.
Why do I get a file name ending in fit?
The download is named after your original file with a fit suffix, so it never overwrites the document you started with.
