Why use this tool
Aims for your size
The tool tries the best quality that still fits 1 MB, and lowers quality step by step only as much as needed.
Private by design
Compression happens inside your browser. Your PDF stays on your device and is never sent to Exam1st or anyone else.
Honest result
If your PDF cannot reach the size without becoming unreadable, the tool says so and shows the smallest size it could make.
When is it useful?
- Upload a longer document, such as a scanned application pack, to a site with a 1 MB limit.
- Email a scanned file that your mail app says is too large.
- Reduce a large notes or paper PDF so it is quick to download and share.
Frequently asked questions
Is compressing a PDF to 1 MB free?
Yes. It is completely free, with no sign-up, no watermark on your file and no payment. It runs in your browser, so you can compress as many PDFs as you like.
How good is the quality at 1 MB?
Better than at 200 KB or 500 KB, because the file is allowed to be bigger. For a few scanned pages, 1 MB usually keeps text clear for reading and printing. For many pages, the tool lowers quality as needed to fit.
What if my PDF has many pages?
More pages share the same 1 MB, so each page gets less. If the result looks too soft, split the PDF into parts with Split PDF and compress each part, or remove pages you do not need.
How is 1 MB counted?
This tool counts 1 MB as 1024 KB. If your form says 1 MB, a file just under this size is accepted. Some sites count 1 MB as 1000 KB, so leave a little room if the limit is strict.
Does compressing change the text in my PDF?
To reach a target size, the pages are turned into images, so the text looks the same but can no longer be selected or searched. If you need selectable text, use the Light level on the main Compress PDF tool, which keeps text but saves less.
Is my PDF uploaded anywhere?
No. Your file is processed on your own device in your browser. Nothing is sent to a server.
