Convert an Image Online

Image formats all store a picture, but they make very different trade-offs — file size, quality, transparency, and how well they scale. Converting between them is one of the most common image tasks: a designer hands you a PNG but the upload form only takes JPG; your camera shoots HEIC or WebP and a colleague needs a plain PNG; or you want the smallest possible file for a fast website. This guide covers what each format is good for and how to convert any one to any other, free and in your browser.

The formats at a glance

• PNG — lossless with transparency. Perfect for logos, icons, screenshots, and anything with sharp edges or a transparent background. Larger files for photos.
• JPG (JPEG) — lossy, small, universal. The default for photographs and almost every upload form. No transparency.
• WebP — modern, ~25–35% smaller than JPG at the same quality, supports transparency and animation. Supported by every current browser.
• AVIF — the newest format, usually even smaller than WebP at the same quality. Great for web performance; encoding support is still growing (Chrome and Edge can create it).
• GIF — old, limited to 256 colours; mainly for simple graphics and short animations.
• BMP — uncompressed bitmap; huge files, rarely the right choice today.
• SVG — vector, not pixels. Scales to any size with zero quality loss. Ideal for logos and icons; not suitable for photographs.

How to convert (any format to any format)

1. Drop your image onto the tool — drag & drop, paste, or pick a file. PNG, JPG, WebP, AVIF, GIF, BMP, and SVG are all accepted.
2. Pick the output format — PNG, JPG, WebP, AVIF, or SVG.
3. Set the quality (for JPG, WebP, AVIF) if you want a smaller file.
4. Download — the preview is the exact file you save.

Everything happens in your browser, so your image is processed on your own device and the conversion is instant.

Which conversion should I use?

• JPG → PNG — when you need transparency or a lossless copy (e.g. to edit further). Note: it won’t add back detail JPG already discarded.
• PNG → JPG — to shrink a large screenshot or graphic for email or a form that caps file size.
• PNG / JPG → WebP or AVIF — the single biggest win for website speed; same quality, much smaller files.
• WebP / AVIF → JPG or PNG — for older software or a form that doesn’t accept modern formats.
• PNG / JPG → SVG — to turn a logo or icon into a crisp, infinitely scalable vector.

Lossless vs lossy — what actually changes

Converting to a lossless format (PNG, SVG) never throws away data. Converting to a lossy one (JPG, WebP, AVIF) re-encodes the pixels; at a high quality setting the result is visually identical to the eye while the file gets much smaller. Re-encoding also strips EXIF/GPS metadata, which is a privacy bonus when sharing photos.

One thing a converter can’t do is recover quality: if you start from a heavily compressed JPG, converting it to PNG gives you a lossless copy of that already-compressed image — not the original detail. Always start from the highest-quality source you have.

Converting to SVG (vectorizing)

SVG is a vector format, so “PNG to SVG” means tracing the image into shapes and paths. That’s perfect for logos, icons, and flat illustrations, which become clean, scalable vectors. Photographs can be converted too, but the result is a stylised, simplified rendering rather than a pixel-perfect copy — for photos, WebP or AVIF is usually what you actually want.
