Convert images online — JPG, PNG, WebP, and HEIC

JPG is the practical choice for most photographs, profile images, online forms, and email attachments. It is widely accepted and usually gives a smaller file than a photographic PNG.

Convert Image to JPG supports PNG, WebP, HEIC, and other browser-readable image formats. If you are starting with a PNG, use the dedicated PNG to JPG converter.

HEIC is common on iPhones, but older sites and many upload portals do not accept it. Convert the photo to JPG first, then choose a size such as 100KB, 150KB, 200KB, or 1MB when the destination has a limit.

WebP is useful when you control the website and want smaller modern image files. It works especially well for many web images, while JPG remains the safer default for broad compatibility.

PNG can be useful for screenshots, graphics, and workflows that require lossless output. It may be larger than JPG, so confirm the upload limit after converting.

Changing an extension is not the same as converting an image. Use a real converter, then set the exact file-size target required by your form or site. For photos, JPG plus a sensible size limit is usually the easiest path.

Need to fit a strict limit? Start with 100KB, 150KB, 200KB, or 1MB.

Check how TargetKB handles KB and MB limits, image quality, transparency and batches before preparing an upload.
