Your application portal just rejected your transcript with "file too large". Drop the PDF here, pick the size the portal demands — 200KB, 300KB, 500KB or 1MB — and download a version that fits. Everything runs in your browser: your grades, certificates and ID scans are never uploaded anywhere.

Transcripts, certificates and scanned documents compress best
Almost every "upload failed" moment in an application comes down to one number. Universities and central application services — students meet them as uni-assist in Germany, UCAS in the UK, Studielink in the Netherlands, Campus France, or a university's own portal in the US and elsewhere — cap the size of each uploaded document to keep their systems fast and storage cheap. Many portals limit a single document to somewhere between a few hundred KB and 2MB, and a fresh scan from a phone or library scanner is often 3–10MB. This tool closes exactly that gap: you state the limit, it walks eight quality/scale settings from sharp down to tiny and downloads the first version that fits.
| Preset | Typical student use | What you get |
|---|---|---|
| 200 KB | Strict per-document caps, single certificates | Legible scan — text clear, seals and stamps soft |
| 300 KB | Application forms, degree certificates | Crisp text — a safe default for most portals |
| 500 KB | Multi-page transcripts, grade reports | Sharp enough for admissions staff to verify grades |
| 1 MB | Essays with images, portfolios, recommendation packs | Near-original look — prints acceptably |
Every portal sets its own number — always use the exact limit your upload page states rather than guessing. The examples below are illustrative; your document's content decides the final quality.
A student scanned their 6-page school transcript at the library and got a 4.8 MB PDF — but the application portal states a 500 KB limit per document (illustrative example). They drop the file, choose the 500 KB preset and press Compress. The tool tries high quality (1.8 scale / 82% JPEG) → 2.9 MB, too big; balanced (1.3 / 68%) → 1.4 MB, still too big; balanced (1.1 / 60%) → 780 KB; compact (0.95 / 53%) → 462 KB — fits. The 462 KB PDF downloads, every grade stays readable at 100% zoom, and the upload succeeds on the first attempt — no deadline drama the night before the closing date.
Exact-size targeting re-renders each page as a JPEG. That is how a precise size is possible — but it means text becomes part of the image (no longer selectable or searchable) and the result works best on scanned or image-heavy PDFs. If your portal requires a searchable PDF, keep the original for that field and use the compressed copy where only a size limit applies.
A dense 30-page scan may never fit 200KB at readable quality. When that happens, the tool tells you the smallest size it reached — pick a larger preset, or split the document and compress each part.
The tool shows the real measured file size — not an estimate. Glance at it, open the file once, and only then upload, so your application goes through first time.
Drop your PDF on the tool above, read the size limit your portal states on its upload page, pick the matching preset (200KB, 300KB, 500KB or 1MB) and press Compress. The tool steps through quality levels and stops at the first one that fits, then downloads the smaller file — ready to upload.
There is no single worldwide number — every university and application service sets its own cap, and many portals limit each document to somewhere between a few hundred KB and 2MB. Always use the exact figure shown on the portal's upload page; the presets here cover the most common limits students meet.
Yes — the tool is portal-agnostic. Whether you upload through a central service like uni-assist, UCAS, Studielink or Campus France, or directly on a university website, the workflow is the same: check the limit the portal states, compress to just under it, and upload the result.
Yes. Coursework uploads to systems like Moodle or Canvas, and school assignment portals, often have per-file limits too. Pick the preset just under your course limit; scanned handwritten pages and image-heavy slides compress the most.
The tool starts at the highest quality that fits under your target and only steps down as far as needed. At 300–500KB, scanned transcripts and certificates stay crisp; at 200KB they stay legible for admissions review. Check the downloaded file at 100% zoom before you submit it.
Here your document is never uploaded at all. Compression runs 100% in your browser tab with JavaScript, so transcripts, ID copies and certificates containing personal data never touch a server — the safest option for application documents.
Yes — unlimited files, no signup, no watermark and no daily caps, forever. Because everything runs on your own device, there is no server cost to pass on to you.
Very dense scans occasionally can't reach the smallest targets at readable quality. The tool then downloads the smallest version it could make and tells you its exact size. Try the next preset up, or split a long document into two PDFs (for example one per certificate) and compress each part.
Size limits in the examples are typical, illustrative values — always use the exact number your portal states. Compression happens entirely in your browser; nothing is stored or transmitted. Researched by PDFBuddyFree Team · Last updated October 23, 2026.
