Compress JPEG Online Free
How to finish the file
- 01
Open FastEdit
Go to app.fastedit.net. The editor loads in your browser, no installation, no account, no signup.
- 02
Load your JPEG
Drag and drop your JPEG file or click to browse. FastEdit reads the file locally, and nothing leaves your machine.
- 03
Adjust quality
Use the quality slider to find the right balance. Quality 75-85 is the sweet spot for most photos, visually indistinguishable from the original while significantly smaller.
- 04
Enable progressive encoding
Turn on progressive JPEG for web-friendly loading. Progressive JPEGs render a low-resolution preview first, then sharpen as the full file loads, giving better perceived performance.
- 05
Export your compressed JPEG
Use the side-by-side compare to verify quality, then click Export. Use fit-to-size if you need to match a specific file size limit.
Benefits
- A typical 5MB JPEG from a phone camera compresses to under 500KB with minimal visible quality loss at quality 80.
- Progressive encoding improves perceived load speed on the web, giving users a preview immediately.
- Side-by-side comparison lets you verify quality before exporting, no guessing.
- Batch processing compresses multiple JPEGs at once with the same settings.
- No watermarks, no hard upload caps, no daily quotas.
Compression Tips
- Quality 75-85 is the sweet spot for most photos. Below 70, artifacts become noticeable. Above 90, file size increases sharply with minimal quality gain.
- Progressive JPEG encoding makes images load faster on the web by rendering a blurry preview first, then sharpening incrementally.
- JPEG is inherently lossy: each re-save degrades quality slightly. Compress from the original source file when possible, not from an already-compressed copy.
- For images with text, sharp lines, or transparency, consider PNG or WebP instead. JPEG introduces ringing artifacts around hard edges.
- Use fit-to-size to automatically find the optimal quality setting for a specific file size target.
Shrink the file, keep the quality in sight, and never hand over the original.
