Our converter supports the widest range of formats — from classic JPG and PNG to modern AVIF and WEBP, HEIC from iPhones and TIFF for print workflows. GD library handles fast JPG/PNG/WEBP conversions, ImageMagick handles all advanced formats, all directly in your browser with no software installation required on any device.
HEIC photos from iPhones and AVIF images can be tricky to handle. Our server-side conversion handles both without any app installation. Upload your HEIC and download a universally compatible JPG or PNG in seconds.
Different formats exist because they're optimized for different jobs, and a file that works perfectly in one context often fails in another. A website that only accepts JPG or PNG will reject a HEIC photo straight from an iPhone, forcing you to convert before you can upload it. A graphic designer might need a PNG converted to ICO to use as a website favicon, or a TIFF converted down to JPG for a faster web preview. Email attachments, older software, and many web forms still don't recognize newer formats like AVIF or WEBP, even though those formats produce noticeably smaller files at the same visual quality. Converting solves these compatibility gaps instantly, without needing a separate desktop application for each format pair.
JPG remains the most universally compatible format, ideal for photos and any situation where you're not sure what the receiving system supports. PNG is the standard choice when you need transparency or lossless quality, commonly used for logos, screenshots, and graphics with sharp edges or text. WEBP offers some of the best compression available today while staying widely supported by modern browsers, making it the smart default for web images where load speed matters. AVIF pushes compression even further than WEBP and is increasingly supported by newer browsers, though older software may not open it yet. GIF is still the format of choice for simple animations and short looping clips. BMP and TIFF are largely used in print, scanning, and professional design workflows where uncompressed or lightly-compressed quality matters more than file size. ICO exists specifically for website favicons and Windows application icons, and isn't meant for general photo storage.
iPhones save photos in HEIC format by default because it stores high-quality images in roughly half the file size of an equivalent JPG, saving storage space on the device. The tradeoff is compatibility – many websites, older Android phones, Windows photo viewers, and most non-Apple software simply can't open a HEIC file directly. Our converter reads the HEIC data server-side and outputs a standard JPG or PNG that opens correctly everywhere, without needing to change any setting on your iPhone or install an app. This is one of the most common conversion needs we see, since almost every iPhone photo shared outside of Apple's own ecosystem eventually needs this conversion at some point before it can be used elsewhere.
Web developers convert PNG and JPG images to WEBP or AVIF to shrink page weight and improve loading speed without a visible drop in quality. Designers convert logos and icons to ICO format when building a favicon for a website, since browsers specifically expect that format in the site's root directory. iPhone users converting HEIC photos to JPG before uploading to websites, sending to Android users, or attaching to forms that don't recognize Apple's native format. Print shops and publishers convert images to TIFF when a high-fidelity, less-compressed format is required for professional printing, while everyday users converting between JPG and PNG simply need the right format for whatever platform or document they're working with.
If your converted image is still larger than you need, Compress Image can shrink the file size further. If you need it at a specific resolution, Resize Image handles exact pixel dimensions or social media presets. And if you only need a portion of the converted image, Crop Image lets you trim it down precisely before using it elsewhere.
Converting between two lossy formats, such as JPG to WEBP, can introduce a very small amount of additional compression if the quality setting isn't matched carefully, since the image is effectively decompressed and re-compressed using a different algorithm. Converting from a lossy format to a lossless one, like JPG to PNG, won't recover any detail that was already lost in the original JPG, but it also won't lose anything further from that point forward. Converting between two lossless formats, or from a high-quality source into a lossy format at a generous quality setting, typically produces a result that's visually indistinguishable from the original. Our converter defaults to quality settings that prioritize keeping the output looking as close to the source as possible, and the quality slider lets you push higher if file size matters less than preserving every bit of original detail, such as when preparing an image for print rather than for the web.
