| Measured fixture results | File reduction: 94.44% · Output size: 92.2 KB · Selectable text retained: 0% · Page 2 preserved: Yes | File reduction: -0.18% · Output size: 1662 KB · Selectable text retained: 100% · Page 2 preserved: Yes |
| Fixture findings | 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. | In the 2-page mixed-content anchor benchmark, the default preset preserved 100% of selectable vector text operators (4/4 headings, 12/12 table cells), but file size was not reduced (1,659 KB to 1,662 KB, -0.18%). |
| Original historical observation | 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). | PDF Resizer accepted the sample without login, processed it in 0.41s on the server, preserved 100% vector text, and exported a 1.62 MB watermark-free PDF (01_landing.png, 02_result.png, 03_download.png). |
| Suitable uses · historical assessment | Already-scanned image-only PDFs where selectable text, copy-paste, and crisp zoom are not needed and local browser processing is preferred | Users needing fast, account-free online document processing with guaranteed 100% text selectability |

| 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). | |
| Interaction restraint | 21 / 30 No login required, but the result screen places a large deceptive ad banner ("DOWNLOAD EXTENSION — 1. Click 'Download' 2. Add Trusted Spot Extension") directly below the workspace that can easily mislead users (02_result.png). | |

| Task quality | 45 / 65 Deterministic PDF stream inspection uncovers a critical flaw: although file size drops from 1,659.0 KB to 92.2 KB (-94.44%, 18.0× ratio) with both pages present, 11zon rasterizes every page into an 816×1056 lossy JPEG bitmap (/Subtype /Image /Filter /DCTDecode), wiping out 100% of vector text operators (bt_operator_count = 0, text_retention_pct = 0.0%) so text can no longer be selected, copied, or searched (45.0/65) | 34 / 65 Size Reduction: --0.18% (1659 KB → 1662 KB, 1× ratio) · Selectable Vector Text Retained: 100% · Page 2 Preserved: Yes |
| Deliverable specifications | 13 / 20 Exports a 92.2 KB 2-page watermark-free PDF with adjustable compression percentage, but full-page 816×1056 JPEG rasterization blurs typography and destroys selectable text (13.0/20) | 18 / 20 Clean unwatermarked export (8/8); Export spec: Full 2-page native vector PDF (1,662 KB, no watermarks) |
