11zon PDF Compressor · PDF compression
Free, login-free on-device compression shrinks the 1.66 MB PDF by 94.44% to 92.2 KB, but flattens every page into an 816×1056 JPEG bitmap (0% selectable vector text retained) and displays deceptive extension ad banners.

Tested result & sample
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).

Experience, rules & trust
- Disclosure
- Does not warn users that vector text pages will be flattened into JPEG images
- Interaction
- 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).

Scoring version 2.3.1 · Test fixture anchor_pdfcompress_v1
Honesty & reputation · 82/100 · 30%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| 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). | Evidence A → |
| 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). | Evidence A → |
| Background & reputation | 17 / 20 | Operated by 11zon (bigpdf.11zon.com), a high-traffic free online document and image utility suite. | Evidence A → |
| Engineering & privacy | 14 / 15 | Executes locally inside the browser via Canvas + jsPDF without uploading the document to a remote server queue. | Evidence A → |
Capability · 72/100 · 70%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| 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) | Evidence A → |
| 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) | Evidence A → |
| Processing speed | 14 / 15 | In-browser Canvas rendering and jsPDF packaging finishes automatically in ~1.85s (14.0/15) | Evidence A → |
Legacy scores may include advertised maximum capabilities. Read tested output separately from paid capabilities. Records without matching tiers and scope are not ranked together.
