When you right-click and save images from websites today, they often save as .webp or .avif files instead of standard JPEGs. Trying to insert these files into PowerPoint, Photoshop, or Word documents often triggers unsupported format errors.

ILoveImages decodes WebP and AVIF files instantly in your browser, converting them into universally supported JPG or PNG assets in a flash.

By utilizing modern browser WebAssembly and HTML5 Canvas pipelines, ILoveImages processes every image locally inside your device memory. This eliminates upload bottlenecks, protects your confidential files from third-party server exposure, and provides lightning-fast execution even on high-resolution camera files.

常见问题解答 (FAQ)

Should I convert to JPG or PNG?

Choose JPG for photos to maintain smaller file size, or PNG if your image contains text, logos, or transparent backgrounds.

Can I use these tools completely offline without an internet connection?

Yes! Once you visit ILoveImages or install it as a PWA, all core scripts and WebAssembly modules are cached locally in your browser's service worker, allowing you to edit photos anywhere, even in airplane mode.

Are my uploaded photos or edits stored on any server?

Never. ILoveImages is built with a zero-server-upload architecture. Every pixel calculation occurs strictly in your browser's local sandbox memory.
