Image Converter — PNG, JPG, WebP, AVIF, HEIC, SVG
Convert PNG, JPG, WebP, AVIF, HEIC, BMP, GIF and SVG images to JPG, PNG, WebP or BMP instantly in your browser. No uploads to external servers — every conversion happens client-side for complete privacy. Ideal for web optimization (convert to WebP), transparency needs (convert to PNG), or universal compatibility (convert to JPG).
The practical decision tree is short. WebP for anything on a website, because it is roughly 25-35% smaller than JPEG at the same quality and every current browser supports it. PNG when you need transparency or when the image is a screenshot, logo, or diagram with hard edges and flat colour. JPEG when you need a photograph to open in something old, or when the receiving system explicitly asks for it. BMP only when an old program insists on it. GIF and AVIF files can be read here but not written, since browsers cannot encode them; SVG is turned into pixels at its own size.

Frequently Asked Questions
What is the best image format for websites?
WebP is the best format for websites in 2025–2026. It provides 25–35% smaller file sizes than JPEG at equivalent quality and supports both lossy and lossless compression, plus transparency. All modern browsers support WebP. Use our converter to batch convert your JPG/PNG images to WebP for faster page loads.
Does converting PNG to JPG reduce quality?
Converting PNG to JPG uses lossy compression, so there is a slight quality reduction. However, at quality settings of 80–90%, the difference is imperceptible to the human eye while file sizes can drop by 5–10x. Note that transparency will be lost since JPG doesn't support it — transparent areas become white.
Can I convert images to WebP without uploading them?
Yes. Our image format converter runs entirely in your browser using client-side JavaScript. Your files never leave your device, making it the most private way to convert images to WebP or any other format. There are no file size limits or upload restrictions.
Is WebP safe to use now?
Yes. Chrome, Firefox, Edge, and Safari have all supported it for years, including on iOS. The remaining risk is not browsers but tooling — some older CMSs, email clients, and desktop applications still refuse it. For a website, WebP is the default choice; for a file someone will download and open locally, JPEG or PNG is safer.
Why did my PNG get bigger when I converted it to JPEG?
That usually means the source was a screenshot, logo, or diagram — flat colour and hard edges, which PNG compresses extremely well and JPEG does not. JPEG is built for photographs, where it wins comfortably. Converting the wrong kind of image the wrong way makes the file larger and adds visible artefacts around text.
