| Measured fixture results | File reduction: 95.31% · Output size: 77.9 KB · Selectable text retained: 100% · Page 2 preserved: Yes | File reduction: 94.44% · Output size: 92.2 KB · Selectable text retained: 0% · Page 2 preserved: Yes |
| Fixture findings | 95.31% size reduction (1,659.0 KB -> 77.9 KB), 21.31x compression ratio, 4/4 headings and 12/12 table cells perfectly preserved without vector rasterization. | Reduced file size by 94.44% (92.2 KB output) across 2 pages, but flattened all pages into JPEG bitmaps with 0% selectable vector text retained. |
| Original historical observation | Aspose Medium preset compressed 1,659.0 KB sample to 77.9 KB (-95.31%, 21.31x ratio); PDF stream inspection confirms all vector text and tables preserved, with one-click wipe available (02_result.png, 03_download.png). | By file size alone (1.62 MB -> 92.18 KB), 11zon looks competitive with Sejda and iLovePDF; however, PDF stream inspection reveals that 11zon flattens every page into an 816×1056 JPEG image (/I0 Do, /I1 Do), turning sharp vector typography and tables into blurry, unsearchable bitmaps (02_result.png, 03_download.png). |
| Suitable uses · historical assessment | Users needing extreme size reduction (-95.31%), high-fidelity vector preservation, and immediate wipe privacy | Already-scanned image-only PDFs where selectable text, copy-paste, and crisp zoom are not needed and local browser processing is preferred |

| Pricing transparency | 30 / 35 100% free and login-free, automatically compressing the uploaded PDF at the default 60% level in ~1.85s (92.18 KB); however, it does not disclose that it rasterizes entire PDF pages into non-selectable JPEG bitmaps (01_landing.png, 02_result.png, 03_download.png). | |
