# Resize Images

> Resize one image or hundreds at once. Exact pixels, percentage, longest side, or social media presets (Instagram, Twitter, YouTube). Files never leave your device.

## How it works

1. **Select images** — Drag and drop multiple images or click to browse and select a batch
2. **Set target dimensions** — Enter desired width and height or select a preset size for all images
3. **Process and download** — Click resize and download all images as a ZIP file

## FAQ

### How many images can I resize at once?

Free users can resize up to 20 images per batch. Premium users get unlimited batch sizes.

### What formats are supported?

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

### Does this preserve EXIF metadata?

EXIF data (camera, GPS, timestamp) survives the resize. Resize re-encodes pixel data, not the metadata block. Toggle "Strip metadata" if you want personal info gone before sharing.

## 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 Resize Images 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.
