Compress PDF to 200 KB

To compress a PDF to 200 KB, select it and tap Compress to under 200 KB. Images are resampled from 150 DPI downwards until the file fits, while typed text stays sharp. In our tests, a 5.16 MB six-page scan came out at 154 KB.

Key facts

Compress PDF to 200 KB is a Documently preset for multi-page academic documents, such as Class 10 and 12 marksheets, semester grade sheets or a certificate with an annexure. The preset brings the whole PDF under 200 KB. Ghostscript, compiled to WebAssembly, runs in the browser and redraws scanned images at 150 DPI, then 120, 100 and lower, down to 40 DPI, stopping at the first step that fits. In our tests, we measured a 6-page scanned PDF of 5.16 MB dropping to 154 KB in 2.6 seconds. Digitally issued marksheets keep their typed text sharp at every step. Black & white mode removes colour from every page, which leaves room for a higher resolution. For a form wanting several certificates in one file, merge first with Merge PDF, then compress once. The PDF never leaves the device. Choose the file, tap Compress to under 200 KB, and check the size on the result card.

200 KB is a common middle limit for application forms — enough for a multi-page marksheet, a set of semester results, or a certificate plus its annexure. It is generous for one page; in our tests a 6-page scan came in at 154 KB with images at 85 DPI. This page is preset to 200 KB and does all the work in your browser, so your documents stay on your phone.

When do you need a PDF under 200 KB?

Typically for academic documents with more than one page: Class 10 and 12 marksheets, consolidated semester grade sheets, degree certificates with a transcript, or a category certificate that runs to two or three pages. Some admission and recruitment forms also use 200 KB for the main document field.

If your form asks for several documents in one file, combine them with Merge PDF first, then compress the merged file here.

How many pages fit in 200 KB?

There's no fixed number — it depends on how the pages were scanned. Page count matters more than anything else: every extra scanned page adds image data, so fewer pages means sharper results. Pages of plain typed text compress much better than coloured marksheets with watermarks and patterned backgrounds.

Black & white mode makes a large difference for multi-page files. Removing colour shrinks every page, so the compressor can keep a higher resolution and the text stays crisper.

What happens to my marksheet during compression?

The compressor uses Ghostscript running as WebAssembly inside your browser. It redraws the scanned images at 150 DPI first, then 120, 100 and lower if needed, stopping as soon as the PDF is under 200 KB. The lowest it will go is 40 DPI.

Anything stored as real text — a digitally issued marksheet from a board website, for example — stays sharp no matter what. If the target can't be reached, the tool says so rather than handing you an unreadable file.

Avoid these common mistakes

Scanning each page as a separate PDF and uploading only one. Merge them first.
Using a phone photo with the page at an angle. Crop and straighten before converting to PDF.
Leaving pages sideways. Fix them with Rotate PDF — a reviewer may reject a document they can't read easily.
Uploading a password-protected PDF. Many portals can't open it.

Frequently asked questions

How do I reduce a marksheet PDF to 200 KB?

Tap Choose PDF, pick the marksheet, and tap Compress to under 200 KB — the target is already set. If it has several pages and the result looks soft, run it again with Black & white on, which usually lets the text stay sharper at the same size.

Can I merge certificates and then compress to 200 KB?

Yes. Use Merge PDF to combine the files in the order the form asks for, download the merged PDF, then open it here and compress. Compressing once after merging gives a better result than compressing each file separately.

My PDF is 5 MB. Can it really get to 200 KB?

Often, yes, if it has only a few pages. In our tests, a 5.16 MB six-page scan came down to 154 KB in 2.6 seconds. A long document with 20 or more colour pages may not get there, and the tool will tell you if it can't.

Will the compressed PDF still print properly?

For screen viewing and form uploads it's fine. Printed on paper, pages compressed to low resolution can look slightly soft. Keep your original file for printing and use the 200 KB copy only for the upload.
