Compress PDF to an Exact Size

Give it a target — 200 KB, 1 MB, anything — and it searches resolution and quality until the file fits, then shows you the achieved size before you download. No “we made it a bit smaller, good luck”.

How it works

Choose your PDF and type the size the portal or mailbox demands.
The tool samples your pages and finds the best quality that fits the byte budget.
It rebuilds the document and shows the achieved size in the result panel.
Check the number, then download. If the target is impossible, it says so instead of failing silently.

Who uses this tool

Exam & admission portalsUPSC, SSC, university portals cap documents at 200 KB–1 MB and reject anything over — to the byte.

Bank & loan applicationsKYC and statement uploads with hard size limits, checked on the spot.

Email attachmentsGet a heavy scan under a 10 MB or 25 MB attachment cap without guessing.

Government e-servicesPassport, PAN and GST portals enforce per-document caps — hit them on the first try.

Job applicationsApplicant tracking systems with per-file limits on certificates and portfolios.

ArchivingShrink scanned archives to a predictable size per document.

🔒 Your files never leave your device

There is no upload step to worry about, because there is no server. The file you choose is processed by your own browser, on your own device, and the result downloads straight from its memory. Once this page has loaded, the tool keeps working with the internet disconnected — try it in airplane mode. Unlike sites that promise to “delete your files after one hour”, there is nothing to delete: your file was never sent anywhere. See how to verify this yourself →

💡 Tips for the best result

Scanned documents compress dramatically; born-digital text PDFs are often already small — the tool tells you if yours is.
Tick grayscale for another significant size reduction on colour scans that don't need colour.
If a long document can't reach the target at readable quality, split it and compress the parts.
The achieved size is shown before download — no need to check in your file manager and retry.
For common targets there are preset pages: 20, 50, 100, 150, 200, 300, 500 KB, 1 MB and 2 MB.

Frequently asked questions

How is an exact target possible when other tools can't do it?

Pages are re-rendered as JPEG images while a search runs over resolution (DPI) and compression quality until the total lands under your target. It's slower than a one-shot preset — and it actually hits the number.

Will the PDF still look the same?

It prints and reads the same, at reduced sharpness for very low targets. Text becomes part of the page image, so it can no longer be selected or searched — the standard trade-off for guaranteed-size compression.

My file is 5 MB and the portal wants 200 KB. Possible?

Usually yes for documents up to roughly 10–15 pages — certificates, marksheets and forms compress well. Very long documents may not fit at readable quality; the tool tells you instead of silently failing.

What if my PDF is already under the target?

The tool returns it untouched and says so — it never inflates a small file just to look busy.

Is my document uploaded to compress it?

No. Compression runs inside your browser tab; it keeps working with the network disconnected.

Is there a file size or page limit?

No fixed limit — your device's memory is the ceiling. Pages are processed one at a time to keep that ceiling high.

Why did the quality drop so much?

Byte targets are physics: 100 KB across 10 pages is 10 KB per page. If the result is too soft, raise the target or split the document — the tool always shows which DPI and quality it used.

Why “compress PDF to 200 KB” is a different problem

Ordinary compressors apply a fixed preset and hand you whatever comes out — 480 KB, 310 KB, sometimes bigger than the input. That's useless against a portal that rejects anything over 200 KB, because the portal doesn't grade effort. Hitting a byte ceiling requires iteration: render, measure, adjust, repeat. This tool automates that loop, sampling your pages at several resolutions, binary-searching the JPEG quality at each one, and only then building the final file — highest quality that fits, verified before you see the download button.

Everything happens on your device. That matters twice over: the documents people compress for portals are ID proofs and financial records, and iterative compression on a server would be slow and metered. Your browser does it in seconds, for free, offline if you like.
