Compress, resize, and convert images in your browser
A private image workflow: compress for email, resize for the web, convert PNG/JPG/WebP, and crop avatars — without uploading photos.
Published 2026-08-07
Camera exports and design PNGs are often too heavy for email caps or CMS limits. A local pipeline — resize, then compress or convert — beats uploading product shots and screenshots to a random converter.
Suggested order of operations
- Crop to the region you actually need (avatars, OG frames, UI chrome).
- Resize to the largest display size you will ship (for example 1600px wide for a blog hero).
- Compress or convert to JPEG/WebP with a quality that still looks sharp at that size.
Format notes
- Image Converter switches among PNG, JPEG, and WebP without a server round-trip.
- AVIF encode is intentionally deferred until canvas support is reliable; decode may still work in capable browsers.
- Animated GIFs flatten to a still frame on canvas export — use a dedicated animation tool when motion must survive.

Frequently asked questions
Are image bytes uploaded when I compress?
No. Image Compressor, Resizer, Converter, and Cropper on Toolverse by RS use the canvas API in your browser.
JPEG or WebP after compressing?
JPEG for broad compatibility; WebP when you control modern browsers and want smaller files. Keep PNG when you need transparency.
