PNG and JPG are what design tools and cameras hand you. AVIF and WebP are what a fast page wants: the same picture, a much smaller file. Smaller images load sooner, cost less bandwidth, and keep a marketing page feeling quick on a phone. This free image converter is the short path from a Figma export, a screenshot, or an iPhone photo to a file you can ship — without sending the image anywhere.
Choose AVIF, drop the file on the card, and download. The converter reads the image on your machine and writes an AVIF at the quality you set.
Switch Convert to WebP. The same pictures encode again as WebP, so you can compare file size against AVIF without exporting twice from your design tool.
Yes — HEIC and HEIF are accepted, along with PNG, JPG, WebP, AVIF, and GIF. Decoding HEIC depends on the browser. Safari reads it natively. Chrome and Firefox may skip a HEIC file they cannot decode; export those as JPG first, then convert.
No. Conversion happens in your browser. The files never go to a server. You need a connection only the first time a format’s encoder loads.
Start at Optimal — it is marked Recommended. Low makes the smallest files. High stays closer to the original. Lossless keeps every pixel, and the file gets larger, which is rarely what you want for photos on the web.
Yes. Scale by a percentage, or set a max width and height. The image fits inside that box, keeps its proportions, and is never enlarged. A 1920px max width is a practical size for most web layouts.
Yes. No account, no watermark. Very large images can still run out of memory in the browser — resize those, or convert them in smaller batches. More free tools are on the tools page.
