Does the quality slider affect PNG files?

No - PNG is lossless, so the slider has no effect. Use WebP or AVIF for lossy-with-transparency.

Will converting JPG → PNG improve quality?

No. Lossy compression already happened in the JPG. Converting to PNG only stores those same pixels losslessly (at a larger file size).

Does PNG → JPG keep transparency?

No - JPEG has no alpha channel. Enable "Flatten transparency" to fill transparent areas with white before converting.

Converting Between PNG, JPG, WebP, BMP, and AVIF

This Image Converter handles every common raster format: drop in a PNG and get a JPG; paste a WebP and export BMP; load any photo and save as AVIF for the smallest possible file size. Everything runs inside your browser using the Canvas API - your image never leaves your device.

  1. Drop an image onto the zone or click to browse (PNG, JPG, GIF, BMP, WebP, AVIF, TIFF, SVG all accepted as input).
  2. Pick your output format from the dropdown.
  3. Choose a resize preset - or select Custom (px) to enter exact pixel dimensions with optional aspect-ratio lock.
  4. For JPG and WebP, drag the quality slider to balance file size against visual quality.
  5. Hit Convert & Download - the result previews instantly and the file saves to your device.

Format Guide

Custom Resize

Select Custom (px) in the Resize dropdown to enter exact width and height values. With Lock ratio checked, adjusting one dimension automatically updates the other to keep your image proportional. Uncheck it to stretch freely.

Frequently Asked Questions

Is AVIF supported in all browsers?

AVIF input (viewing) is widely supported. AVIF output encoding via Canvas requires Chrome 94+ or Firefox 93+. If your browser cannot encode AVIF, this tool shows a warning and recommends WebP as the next-best option.

Why is my BMP file so large?

BMP stores raw uncompressed pixel data - a 1920×1080 image takes about 6 MB. It is the right choice when you need full fidelity and the receiving software only accepts BMP (e.g. some Windows GDI applications). For everything else, PNG gives lossless compression at a fraction of the size.

Can I convert SVG or GIF files?

SVG and GIF are accepted as input - the browser renders them onto a canvas which is then exported to your chosen format. Note: animated GIFs export only the first frame. SVG vector detail is rasterised at the SVG's natural dimensions.

What is the maximum file size this tool handles?

There is no hard limit - the practical ceiling is your browser's available memory. Very large images (above 30–50 megapixels) may be slow depending on your device. For batch processing of many files, a command-line tool like ImageMagick is faster.
