How Browser-Based Image Conversion Works
AI Toolbox uses the HTML Canvas API to decode your image and re-encode it in the format you choose — entirely inside this page. Your files never reach a server.
How to Convert an Image
Upload your image
Drop a JPG, PNG, WebP, BMP, GIF, AVIF, or TIFF file into the upload area, or click to browse.
Pick the output format
Choose PNG for transparency, JPEG for small photo files, or WebP for modern compression. Adjust quality for JPEG and WebP.
Convert and download
Click Convert. The new file is generated locally and downloads to your device — no upload, no waiting.
Why use AI Toolbox Image Converter?
Local Conversion
Conversion happens in your browser using the Canvas API. Files are never uploaded to a server, so private photos and ID documents stay on your device.
Format Flexibility
Read JPG, PNG, WebP, BMP, GIF, AVIF, and TIFF. Output PNG, JPEG, or WebP — three formats that cover almost every web and document workflow.
Quality Control
Adjust JPEG and WebP quality with a single slider. PNG output stays lossless when you need pixel-perfect transparency or sharp text.
Instant Output
No queue, no upload bar, no email link. The converted file is ready to save the moment your browser finishes encoding it.
Frequently Asked Questions
Is this image converter really free?↓
Yes. There are no costs, watermarks, file limits, or accounts. Convert as many images as you want.
Are my images uploaded to a server?↓
No. The conversion runs in your browser using the Canvas API. Your image never leaves your device.
Can I convert PNG to JPG?↓
Yes. Drop a PNG file, choose JPEG as the output, and download the result. Note that JPEG does not support transparency, so transparent areas will become opaque.
Can I convert JPG to PNG?↓
Yes. Drop a JPG, choose PNG as the output, and download a lossless PNG copy. PNG cannot recover detail lost during the original JPEG compression, but no further loss is added.
Does the WebP converter work in every browser?↓
WebP encoding is supported in modern Chrome, Edge, Firefox, and Safari. If your browser cannot encode WebP, the tool falls back to PNG and shows a notice.
What input formats are supported?↓
JPG, PNG, WebP, BMP, GIF, AVIF, and TIFF — anything your browser can decode through an Image element.
What is the maximum file size?↓
Up to 50 MB per image. Larger images may run out of browser memory while encoding.
Why does the quality slider only affect JPEG and WebP?↓
PNG is a lossless format — it does not use a quality factor. JPEG and WebP are lossy and benefit from a quality setting that trades file size against detail.
