Our side by side test
We took a 9 page PDF of handwritten notes, photographed on a phone, 8.25 MB in total. We compressed it with iLovePDF using Recommended compression, and with our own Recommended mode.
iLovePDF returned 832 KB. We returned 707 KB, about 15% smaller. Then we compared every page with the original using SSIM, a standard image quality score. Our pages scored higher on 8 of the 9 pages, because we kept more resolution and tuned each photo separately.
| iLovePDF Recommended | PDF File Compress Recommended | |
|---|---|---|
| File size | 832 KB | 707 KB |
| Image width per page | about 1090 px | about 1270 px |
| Average SSIM vs original | 0.949 | 0.960 |
| Pages with higher quality | 1 of 9 | 8 of 9 |
What works differently
- Your browser compresses the file. iLovePDF processes it on its own servers.
- You can type an exact limit such as 100 KB, 200 KB or 1 MB instead of picking a preset.
- We tune every photo and scan on its own, so we spend quality where you will see it.
- The page keeps working offline once it has loaded, with no upload wait on slow connections.
When iLovePDF fits better
iLovePDF bundles many tools, such as merge, split, convert and edit. We focus on one job: making PDFs smaller. Use iLovePDF when you need its other tools, and come here when you want a smaller file that stays private.
