Accepted: common bitmap formats (PNG, JPEG, WEBP, AVIF*) supported by your browser.

Target format

Quality (JPEG/WEBP/AVIF): 90%

Resize

Width (px)

Height (px)

Percent (%)

DPI (for print calc)

Background for opaque formats (JPEG/AVIF)

apply background when needed

Transparency is preserved for PNG/WEBP if supported; JPEG/AVIF are opaque.

Notes:

Compress a phone photo for web: Drop a JPEG ? Preset "Web JPEG 1920px @ 0.80" ? Convert ? Download. Expect ~60-85% smaller.
Keep transparency: Drop a PNG with transparent logo ? choose PNG or WEBP ? Convert. JPEG/AVIF would need a background color.
Tiny preview: Drop any photo ? Resize: "Limit long edge" 800 ? WEBP 0.60 ? Convert.
AVIF (if supported): Use "AVIF 1600px @ 0.55" preset for even smaller files; decode can be slower on older devices.

* Browser support for export varies. This page detects support and disables unsupported targets to avoid surprises.

Quick guide

Format	Use When	Pros	Caveats	Typical Settings
PNG	Logos, UI, line art, text, needs transparency.	Lossless; crisp edges; universal support.	Larger files for photos.	Lossless (no quality slider). Consider resizing.
JPEG	Photographs/screenshots without transparency.	Small files; fast decode; ubiquitous.	No transparency; artifacts at low quality.	Quality ~0.70-0.85 for web; resize to =1920px.
WEBP	Modern web; supports lossy + transparency.	Smaller than JPEG; can keep transparency.	Older browsers may not fully support export.	Quality ~0.60-0.80; keep transparency if needed.
AVIF	Smallest files for photos/graphics (if supported).	High compression efficiency; decent quality.	Slower encode/decode; support varies.	Quality ~0.45-0.65; test visual result.
GIF/TIFF/BMP/ICO/HEIC	Specialized workflows.	-	Not reliably exportable from the browser canvas.	Use server/WASM encoders if you need these.

This tool converts single still images. Animated formats and metadata preservation are out of scope for a pure-browser converter.
