How to Compress a PDF to 200 KB (Rebuild from JPG)

To compress a PDF to 200 KB, work out how many KB each page can have, then make every page that small. Try Compress PDF on Strong first (a Pro tool you can try free on PDFs of up to 2 pages). If the scan is still too big, rebuild it: turn each page into a JPG, compress it to your per-page budget with the free image compressor, and rejoin the pages with the free JPG to PDF converter.

200 KB is a common cap for marksheets, experience letters, address proofs and other supporting documents on admission, recruitment and government portals. It's small, but for one to three pages of printed text it's very doable once you stop thinking about the file and start thinking about the pages.

Start with a per-page budget

Divide the limit by the number of pages, and keep about 10% spare:

Pages	Budget per page	Realistic?
1	about 180 KB	Easy for almost any document
2	about 90 KB	Fine for printed text at a modest resolution
3	about 60 KB	Possible for plain text pages, in greyscale
4 or more	45 KB or less	Hard; text gets blurry. Check if separate uploads are allowed

The budget tells you which route to take. One page at 180 KB is mostly about shrinking an oversized scan. Three pages at 60 KB each means low resolution, and you'll want control over every page, which is what the rebuild gives you.

Typed PDFs (exported from Word, or downloaded e-certificates) are often under 200 KB already. Check the size before you do anything: in File Explorer it's in the Size column, on a Mac use Get Info. If it's already under, upload it as it is. Compressing a text PDF won't make it much smaller anyway.

Route 1: Compress PDF on Strong

1. Open Compress PDF and sign in. A free account can try it on PDFs of up to 2 pages.
2. Set How much to compress to Strong: smallest file, lower image quality.
3. Click Choose a file, pick the PDF, and click Start.
4. Click Download result and check the new size in your file manager.

Strong keeps about 100 pixels per inch of each page and re-saves the scans as JPEG at a lower quality. A one-page colour scan of a few MB often comes down a long way. If it lands under 200 KB, you're done. If it doesn't, the rebuild below gives you finer control, because you pick the exact width and quality for each page.

Route 2: Rebuild the PDF from small JPGs (free)

Everything here runs in your browser; nothing is uploaded.

1. Turn the pages into images

Open the free PDF to JPG converter and choose your PDF. For budgets of about 80 KB a page or more, pick High (150 dpi) (an A4 page is about 1240 × 1754 pixels) and size it down in the next step. For tighter budgets pick Screen (96 dpi): about 794 × 1123 pixels, readable and already small.

If you only have paper, photograph each page flat in daylight instead and crop it with the free image cropper.

2. Resize to the width your budget allows

Use the free image resizer with proportions locked:

Per-page budget	Width to try (A4 portrait)
150-180 KB	1100-1200 px
80-100 KB	900-1000 px
50-70 KB	750-850 px

3. Compress each page to its budget

Open the free image compressor and add all the pages at once (up to 20). Set Save as to JPG and the quality slider to about 70%, then compress. The size of each page appears next to it. If any page is over budget, move the slider down to 60% and compress again. Below 50%, text starts getting blocky edges; shrink the width a little instead.

Pages with photos, coloured seals or busy backgrounds will be heavier than plain text pages. That's fine as long as the total fits: a 120 KB photo page and a 60 KB text page still make 180 KB.

4. Put the PDF back together

Open the free JPG to PDF converter, add the compressed pages, check the order with ↑ and ↓, choose A4 and a Small margin, and click Create PDF. The size is shown next to the button before you download.

JPGs go into the PDF as they are, without being re-saved, so the PDF is only a few KB more than the pages added up. You can predict the result before you make it.

A worked example

A 3-page marksheet bundle, scanned in colour at 300 dpi, is 2.4 MB. The portal allows 200 KB.

• Budget: 200 × 0.9 ÷ 3 = 60 KB per page.
• PDF to JPG at Screen (96 dpi): pages come out roughly 794 px wide.
• Compress as JPG at 65%: the two text pages land around 45-55 KB, the page with a coloured photo around 70 KB. Total about 170 KB.
• JPG to PDF: a PDF of about 175 KB.

Your numbers will differ, but the method is the same: aim under budget per page, check the total, adjust the heaviest page.

What you give up

The rebuilt PDF is pictures of pages. Any real, selectable text (for example in a downloaded e-certificate) becomes part of the image, so it can't be copied or searched. That rarely matters for an upload a person will look at, and a typed PDF is usually small already.
