PDF size reducer: compress a PDF to any KB or MB

Choose a PDF and type the limit in KB or MB, such as 200 KB, or pick Small, Medium or Large.

What this tool does

Upload forms often set a maximum size for a PDF, such as 200 KB or 2 MB. This tool turns each page into a lighter picture and builds a new PDF, so it can reach very small sizes. Type the size you need, or pick Small, Medium or Large and see the real size before you choose. Every page is kept, in the same order. Choose up to 25 PDFs at once to make them all the same size.

How it works

  1. Choose the PDF, or several at once (up to 25).
  2. Pick Small, Medium or Large, or type the exact size the website asks for. A single PDF shows the real size of each choice.
  3. Check the preview and download. With several PDFs you get a Download button for each one, and one ZIP with all of them.

Questions and answers

How does it make the PDF so small?

Each page is turned into a picture at a lower sharpness, then saved as a new PDF. Each page becomes a picture. Text can no longer be selected, and form fields, links, bookmarks and digital signatures are not kept. Keep your original.

Can I type the size I need?

Yes. Type any size in KB or MB, for example 75 KB. The PDF is made as clear as possible while staying under that number. It gets under the size you type, not exactly onto it.

Can I compress several PDFs at once?

Yes. Choose up to 25 PDFs at once, in the file picker or by dragging them in. One size is used for all of them. They are made one after another on your device, and then you get a list with a Download button for each PDF and one ZIP with everything. If you choose more than 25, the first 25 are used. Each PDF is made smaller on its own: the tool does not join PDFs into one file. A batch of 25 ten-page PDFs takes 1 to 2 minutes on a computer with a typed size, and much less with Small, Medium or Large; a phone can take several times longer. See Compress several PDFs at once.

What happens to a PDF that is already small, or locked?

A PDF that is already under the size you type is kept unchanged, and marked "Already small enough". A PDF that needs a password to open cannot be changed here. With several PDFs it is skipped with a plain message and the others carry on. Save a copy without the password in your PDF app first. If a size cannot be reached, the list shows the smallest size we could make.

Will it still be readable?

For typical documents, yes. The preview shows the result before you download it. "Black & white" makes text documents even smaller.

Is my PDF uploaded?

No. Each PDF is made on your own device, one after another, and the ZIP is made on your device too.
