Compress a PDF to 200 KB or less, a common ceiling on application portals, exam boards and document-upload forms for banks and ID checks. This page opens with the target at 200 KB, which gives each page twice the room of a 100 KB limit, so a short scan of a certificate, mark sheet or ID card can keep more of its detail. Three JPEG quality levels are tried, the highest that fits is used, and the size reported is the real file’s. Pages become images, so text is no longer selectable. The PDF never leaves your device.
How it works
- Drop the PDF, or several if you have more than one document to upload; each gets the same 200 KB target.
- Leave the target at 200 KB, or type the exact number your form states. Pages are rendered at 108 dpi and the JPEG quality is searched for the best fit.
- Download, then check the result line: it shows the old and new size, or says plainly that 200 KB was not reachable.
Questions
- How do I get a PDF under 200 KB for an upload form?
- Drop it here and press Compress & download; the 200 KB target is already set. Pages are re-encoded as JPEG at the highest quality that fits, and the result line confirms the final size. If the form only needs some of the pages, remove the rest first with the PDF page organizer: fewer pages leave more of the 200 KB for each one.
- Is 200 KB enough for a scanned document?
- It depends on the page count more than anything. 200 KB over 4 pages is 50 KB a page; over 20 pages it is only 10 KB a page. If even the lowest quality the tool tries, 35%, overshoots, you get that smallest version and a warning, never a file that silently misses the limit.
- Why does the compressed PDF have no selectable text?
- Because each page is now a picture. Hitting a fixed size reliably means re-encoding pages as JPEG images, which flattens the text into pixels. For an upload that someone will read, that is usually fine. If you need the words back as text, the PDF to text tool can read them with on-device OCR.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Is merge/split lossless?
- Yes. Merging, splitting, reordering and rotating copy pages intact: text stays selectable, links keep working, quality is untouched. Only the compress pages re-encode content, and they say so.
- How strong is the password protection?
- Without the password the file cannot be opened. The cipher follows the PDF’s own version: AES-128 for PDF 1.6 and 1.7, and the older RC4 cipher for other versions. Choose a real password: the encryption is only as strong as it.
- Can it compress any PDF to 100 KB?
- No, and it will not pretend to. Image-heavy pages compress well; a born-digital text PDF may already be near its floor. The tool reports the size it achieved rather than silently overshooting.
