Shrink Text-Heavy PDFs — A 13MB Property Register Down to 1MB (Image-Conversion Compression)
Jun 23, 2026
Tried to email a document only to be blocked by "file too large"? The frustrating part: running a text-only PDF through a normal compressor often barely changes the size. Documents that are mostly text — property registers (등기부등본), terms, contracts — have no images to shrink. That's where the "image-conversion" method comes in. For example, a 13MB property register can drop to about 1MB — a 90%+ reduction.
Just pick "Strong (image conversion)" as the method — even text-heavy PDFs shrink dramatically. Free, no sign-up.
Compress a PDF →Why won't a text-heavy PDF compress?
Normal PDF compression (downsampling) reduces size by shrinking the photos and images inside the PDF. But documents that are mostly text and vectors — property registers, terms, contracts, court rulings — have almost no images to shrink. So a normal compressor often reports "already optimized" and leaves the size unchanged.
The fix — the "image-conversion (PDF→JPG→PDF)" method
This method turns each page into an image (JPG) and reassembles them into a PDF. Since the text becomes a single image, even documents that wouldn't budge under normal compression shrink a lot.
- Effect — Greatest on text-heavy documents. For example, a 13MB property register → about 1MB, a 90%+ reduction (varies by document and strength).
- Trade-off — Because text becomes an image, you can't select, search, or copy text. It's ideal when you only need a smaller file to email or upload; if you need to search or edit the text, use the standard method.
How to compress — 3 steps
- Pick the method — In PDF compression, set the method to "Strong (image conversion)."
- Pick the strength — Light, Standard, or Strong. Higher means smaller but can blur the text, so "Standard" is usually enough.
- Upload & download — Upload the PDF and the "original → result" sizes show side by side. Download the smaller PDF and you're done.
Which method, when?
| Document | Recommended method |
|---|---|
| Property register, terms, contracts (text-heavy) | Strong (image conversion) |
| PDFs with many photos or scans | Standard compression is enough |
| When you must keep text searchable/copyable | Standard compression |
Tools that work well together
For how to choose a general PDF compressor, see recommended free PDF compression sites. To pull PDF pages out as image files entirely, use PDF → image conversion.
One "Strong (image conversion)" pass lightens even a property register. Free.
Compress now →Frequently asked questions
Q. Does 13MB really become 1MB?
Text-heavy documents often shrink that much, but the result depends on the content and strength. After compressing, the "original → result" sizes are shown so you can see the actual result.
Q. Does the text get blurry?
Higher strength means smaller files but can blur the text. "Standard" is usually clear enough to read.
Q. Can I still search or copy text afterward?
No — with image conversion the text becomes an image, so search and copy won't work. If you need to keep the text, use the standard method.
Q. Is it free? Is my file stored?
It is free, and uploaded PDFs are deleted from the server right after processing and are not retained.
