Why use this converter

Privacy First

Unlike other converters, we don't upload your files to our servers. All processing is done client-side.

Runs in the Browser

Each image is converted with the Canvas API on your device, one file at a time.

Modern Formats

Stay ahead of the curve with support for next-gen formats like WebP and AVIF for better web performance.

Pixel Safety Cap

There is no daily quota. Images wider or taller than 16,384 pixels, or over 80 million pixels, are skipped so the tab stays stable.

Batch Queue

Add several images, convert them in order, then download each file or a ZIP of the results.

Quality You Set

The slider affects JPEG, WebP, and AVIF. PNG output stays lossless. Animated files keep the first frame only.

Quality & Compatibility Strategy

JPG to ICO works best when you start near quality 90-100 and validate with real assets.

ICO supports transparency, but JPG sources usually do not include alpha data. Neither format is primarily animation-focused for this route. Expect larger files unless quality and dimensions are reduced.

Useful for icon specific output for favicons and app icons
