Compress PDF to 200 KB

A 200 KB ceiling shows up often on online applications for jobs, admissions, scholarships and government recruitment. It gives you roughly twice the room of a 100 KB limit, which is often the difference between a blurry scan and one where every line is easy to read. This page starts with 200 KB selected.

Where 200 KB limits appear

Forms tend to use 200 KB for single documents that reviewers check by eye: a cover letter, an experience certificate, a no-objection letter or a one-page declaration. As an example from Indonesia, the 2023 CPNS FAQ from BKN listed 200 KB for the photo, selfie and ID card uploads, larger limits for diploma and transcript PDFs, and noted that requirements vary by institution. That is the general pattern everywhere: each document slot can have its own limit, and the current announcement for your application is what counts.

How the tool reaches 200 KB

Your PDF is opened in the browser with PDF.js. Each page is drawn as an image and the document is rebuilt with JPEG pages using pdf-lib. The tool starts with a render scale of 1.2 and JPEG quality of 78%, then steps down only if the file is still too big. It stops as soon as the output is under 188,000 bytes, which is 200 KB (200,000 bytes) minus a 6% margin.

The result panel shows the original size, the new size and how much was saved. If no setting gets under the target, you still receive the smallest candidate along with a clear message.

Scanned versus typed PDFs

A scanned document is already a picture, so turning it into JPEG pages costs nothing in function and usually saves a lot of space. A two to four page scan commonly fits 200 KB with readable text.

A typed PDF exported from a word processor is a different case. It is often already small, and after this tool it becomes image-only: no text selection, no search, no clickable links, no form fields and no digital signature. If your typed file is already under 200 KB, you do not need to compress it at all. Check first with check PDF size.

Tips for a clean result

• Scan on a flat surface in good light; shadows and gradients take extra bytes.
• Crop off empty margins before making the PDF.
• Upload only the pages the slot asks for.
• Name the file plainly, for example experience-certificate.pdf, so it is easy to match to the right slot.
• If a long document will not fit, consider compressing to 500 KB only when the form allows it.

All of this happens on your device. Nothing is uploaded, and there is no sign-up or daily limit. The receiving portal's current instruction remains the final authority on what it accepts.
