Your files never leave your browser
200KB is the sweet spot that a lot of people should be aiming for instead of 100KB. It is a common cap on job portals, university submission forms, and internal document systems, and — importantly — it is a target that scanned documents can realistically hit without turning the text into unreadable mush. The difference matters: squeezing a two-page scan down to 100KB usually means dropping image quality to the point where small print blurs, while 200KB typically leaves enough headroom that the document still reads cleanly on screen and in print. This tool optimises your PDF's internal structure in the browser, which works well on text-based PDFs like exported reports, invoices, and forms filled in digitally. Scanned pages are a different problem — their size lives in the embedded page images, which browser-side optimisation cannot re-encode. If your file is a scan and it lands well above 200KB here, the practical fix is upstream: rescan at 200 DPI rather than 600, choose greyscale instead of colour if the original is black text on white, and avoid 'photo' scan modes that force high-quality JPEG compression on every page.
The most widely used cap
200KB is the default document limit across a large share of Indian recruitment and university portals, and it is a far more forgiving target than 100KB. It is roughly the point at which a two-to-four page text PDF, a scanned single-page certificate at moderate resolution, or a mark sheet exported directly from a university portal will all comfortably fit. If you have a choice of caps to work to — some portals list a range — 200KB is usually the sweet spot between file size and keeping a scan sharp enough to read.
Multi-page documents at 200KB
Size scales with page count in a way people consistently underestimate. A single scanned page that lands at 180KB means a five-page version of the same document will be near 900KB, and no amount of structural compression closes that gap. When a portal caps a multi-page upload at 200KB it is usually expecting a text-based export rather than a scan. If you must submit scanned pages, compress each page as an image before assembling the PDF, or check whether the portal accepts separate uploads per page — many do, and per-page limits are far easier to satisfy than a single combined one.
Frequently asked questions
- Is 200KB enough for a multi-page PDF?
- For text-based PDFs, comfortably — a ten-page Word export often sits under 200KB. For scanned pages, generally not: budget roughly 100–200KB per scanned page at readable resolution, so anything beyond one or two pages will exceed the cap.
- Why did my PDF barely shrink?
- Because it is image-heavy. Structural optimisation removes redundancy in the PDF container — fonts, unused objects, stream encoding — and a scanned PDF has very little of that. Almost all of its bytes are JPEG data this tool deliberately leaves untouched.
- Should I aim for 200KB even if the limit is higher?
- There is no benefit to compressing below what the portal requires. Every reduction on a scanned document trades away legibility, and a rejected upload for being unreadable is worse than a larger file. Compress to fit the stated limit, not below it.
- Does compressing twice make the file smaller?
- No. Structural optimisation is idempotent — once redundancy is removed there is nothing further to remove, and a second pass returns a near-identical file. If one pass did not reach your target, a second will not either.
- Will the portal detect that my PDF was compressed?
- There is nothing to detect. The output is an ordinary, valid PDF; compression is a normal part of how every PDF writer works. No metadata flags the file as having been processed.
- My PDF got slightly larger after compression. Why?
- Occasionally a file is already optimally packed and rewriting it adds a small amount of structural overhead. When that happens, keep your original — the tool shows both sizes so you can see it plainly rather than assuming an improvement.
