⚡ Try with a sample photo
Convert between every common image format without uploading your photos. JPG, PNG, WebP, HEIC, AVIF, GIF, BMP — any to any. The conversion happens in your browser using the built-in encoders, so nothing touches a server, there is no watermark, and there is no file-count limit. Drop in a batch and pull out a zip of converted files in seconds.
Why a local image converter beats the uploady kind
Most online converters upload your file, re-encode it on their server, and hand it back. That round-trip is slow and leaks your images through their logs. It is particularly bad for HEIC files from iPhone, which are often photos of IDs, receipts, or personal documents you do not want in a stranger's database. This converter runs entirely on your device. Nothing is uploaded. You can convert hundreds of files without hitting a quota or watermark.
Which format should I pick?
Short version: WebP for the web (smallest file at the same quality, supported by every modern browser). JPG for photos going to email or print (maximum compatibility). PNG when you need transparency (logos, cutouts, screenshots of UI). AVIF if you need the absolute smallest file for the web and your destination supports it. HEIC is Apple's efficient photo format — convert away from it for sharing, convert to it only if you need to match an iPhone camera roll.
Batch conversion and chaining with other tools
Drop in a whole folder of photos and convert them in one pass. The output is a zip of the converted files named to match the originals. If you want smaller files on top of converting, chain with the image compressor. If you want to also resize to a target pixel size, hit resize before converting. Everything runs locally, so the chain is fast and private.
Common ways people use it
Convert HEIC from iPhone to JPG or PNG
HEIC does not upload cleanly to many services. Convert your iPhone photos to JPG before sending to a PC user, uploading to an old CMS, or emailing.
PNG screenshots to WebP for the web
Screenshots are usually PNG, which is huge. Convert to WebP and the same visible quality comes in at a fraction of the file size.
Batch-convert a product photo folder
Export your Shopify or Etsy product folder as WebP in a single pass so every listing loads fast without individual edits.
GIF to MP4 or WebP for smaller animations
Animated GIFs are heavy. Convert to WebP or MP4 and the same animation looks identical at a fraction of the size.
