Image Converter for JPG, PNG, and static WebP

Add the file, choose a target, and run the Image Converter. It decodes the source pixels, creates a new JPG, PNG, or WebP Blob, checks the output signature and MIME type, and enables download only when those bytes match the requested format. Renaming .png to .jpg does not perform this work.

JPG has no alpha channel. The Image Converter composites every fully or partly transparent pixel onto your selected background color before encoding. That choice is permanent in the new JPG, so keep the original PNG if you may need transparency later.

No. JPG to PNG creates a lossless PNG from the pixels the browser can decode, but it cannot reconstruct detail removed by earlier JPEG compression or recover an alpha channel that never existed. It can be useful when an editor requires PNG or when you want to avoid another lossy save.

Formats compress different content in different ways. JPG photographs often become compact, while a JPG to PNG conversion may grow because PNG preserves decoded pixels losslessly. A small flat-color PNG can also become larger as lossy WebP or JPG. Compare the measured sizes instead of assuming a new extension must be smaller.

Yes, for static files when the browser can decode the source. PNG to WebP is offered only after a test encode produces a Blob whose MIME type and signature are truly WebP. WebP to PNG uses the decoded still pixels and creates a verified PNG.

This browser Canvas workflow does not copy source EXIF, GPS, IPTC, XMP, comments, or original print-resolution metadata into the new file. It preserves visible decoded pixels and pixel dimensions. Treat the downloaded file as a new asset and separately review its appearance, filename, and sharing destination.

No. The first version detects animation chunks in PNG and WebP and reports an individual failure. It does not quietly capture the first frame and claim the animation converted successfully. Use a frame-aware animation tool when timing and every frame need to survive.

Yes. Add up to 20 still images, choose one shared target and its settings, then run the batch. Each image keeps its own detected properties, result size, success state, download button, or exact failure reason. One bad file does not hide the successful outputs.

The image decoding, Canvas rendering, encoding, comparison, and download happen in the current browser session; the tool does not intentionally send image files to a conversion server. The website can still load normal page resources, ads, and analytics, and files you later share follow that service's policies.

Choose JPG for opaque photographs when broad compatibility and adjustable lossy quality matter. Choose PNG for transparent logos, screenshots, text, and sharp graphic edges. Choose verified WebP for modern web delivery when its size-to-quality balance and optional transparency fit the destination.
