Image Converter - HEIC, PNG, JPG & WebP Conversion

Image formats are not interchangeable, and the wrong one causes real friction: an iPhone HEIC photo that a Windows form refuses to accept, a PNG screenshot too heavy to email, a WebP graphic that an older CMS will not display. This converter changes images between HEIC, PNG, JPG, and WebP directly in your browser, so the file you have becomes the file the destination wants — without installing software or sending your pictures to a server. HEIC (High Efficiency Image Container) is the headline case. iPhones and iPads have shot HEIC by default since iOS 11 because it stores photos at roughly half the size of JPG, but support outside the Apple ecosystem is still patchy. When you select a HEIC file here, the tool loads the heic2any decoding library on demand and converts the photo to your chosen format entirely on your device — the standard fix for "this site does not accept HEIC" moments. For PNG, JPG, and WebP sources, the browser decodes the image onto a canvas and re-encodes it in the target format at the quality you set; when converting to JPG, which cannot store transparency, any transparent regions are flattened onto a white background rather than turning black. Each format has a job. PNG is lossless and supports transparency, making it right for logos, UI screenshots, and graphics with text or sharp edges — at the cost of large files for photographs. JPG is the veteran lossy format: excellent for photos, universally supported, but incapable of transparency. WebP is the modern all-rounder, typically 25–35% smaller than JPG at similar quality and able to carry transparency like PNG; its only weakness is legacy software that predates it. If you are unsure, the format picker below the converter turns those trade-offs into a two-second decision: toggle whether your image needs transparency, whether it is a photograph, and whether it must open absolutely everywhere, and it suggests a format with a one-line justification. Because every step — file reading, decoding, encoding, downloading — runs as JavaScript in your own browser, the tool is private by construction. No upload, no queue, no account, no watermark, and it keeps working offline once the page is loaded. Converting is re-encoding, though: repeated lossy conversions gradually degrade quality, so convert from your original file when you can and keep it as the master copy.
