Is WebP supported everywhere?

Every current browser supports displaying WebP. Some desktop email clients and older design software still do not, so choose JPEG when the destination is email.

Why is AVIF not offered?

Browsers can decode AVIF widely but cannot reliably encode it from Canvas, which is what keeps this tool fully client-side. Offering it would mean uploading your images to a server, which we are not willing to do.

Will converting reduce the file size?

Usually yes when converting to WebP. If you need a specific size budget rather than a specific format, use the Image Compressor instead.

About this tool

Different jobs want different image formats. WebP gives the smallest files and is supported by every current browser, making it the right default for websites. JPEG remains the safest choice for email and older software. PNG preserves transparency and is lossless, which matters for logos, icons and screenshots with sharp edges. This converter re-encodes your images locally using the Canvas API, so nothing is uploaded and conversion is effectively instant.

How to use

Choose the format you want to convert to.
Adjust the quality slider for lossy formats — 85 is a good default.
Drop in one or more images.
Review the plan, then click Convert.
Download the files individually or as a ZIP.

When to use this tool

Converting photos to WebP to speed up a website.
Turning WebP images into JPEG for software that cannot read WebP.
Converting screenshots to PNG to keep text crisp.
Standardising a mixed folder of formats before handing it to a client.

Tips

Converting to JPEG flattens transparency onto a white background, because JPEG has no alpha channel.
Quality above 90 rarely looks better but grows the file noticeably — 80–85 is the sweet spot.
Converting between lossy formats re-compresses the image; convert from your original whenever possible.

Limitations

AVIF encoding is not supported by all browsers and is therefore not offered.
