# Compress Images Without Losing Quality

> Most online compressors upload your photos. This one shrinks PNG, JPG, and WebP files up to 50 MB with a quality slider and a live before-and-after preview, all in the tab. EXIF survives by default with an opt-in strip toggle for camera, GPS, and timestamp blocks. Canvas API handles it.

## How it works

1. **Select image** — Drop the image you want to shrink, or click to browse
2. **Choose compression level** — Select quality level or target file size
3. **Download** — Get your compressed image instantly with size reduction stats

## FAQ

### How much can images be compressed?

Typical compression reduces file size by 50-80% with minimal visible quality loss.

### What formats are supported?

PNG, JPG/JPEG, and WebP images up to 50MB.

### Does this preserve EXIF metadata?

EXIF survives by default. JPEG output keeps the full metadata block; toggle "Strip metadata" to scrub camera, GPS, and timestamp before sharing photos publicly.

## Tips

- **Use the live before/after preview** — Drag the quality slider and watch both sides of the preview to find the lowest setting that still looks clean before downloading.
- **Strip metadata for a smaller file** — JPEG output keeps EXIF by default. Toggle Strip metadata to drop camera, GPS, and timestamp blocks and shave extra kilobytes.
- **Source image never uploads** — Compression runs in your browser against PNG, JPG, and WebP up to 50 MB — the file does not leave the tab.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Compress Images Without Losing Quality runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
