Which image format should you use?
There’s no single “best” image format — the right choice depends on what you’re doing. PNG is lossless and supports transparency, making it ideal for screenshots, logos, graphics, and any image you’ll edit. JPG uses efficient lossy compression and is the universal choice for sharing photographs. WEBP and AVIF are modern web formats that produce smaller files than JPG or PNG at similar quality, which is why they’re increasingly used on fast websites. HEIC is Apple’s space-saving photo format — great on an iPhone, but awkward to open elsewhere, which is the most common reason people convert.
What is HEIC, and why convert it?
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used by default since iOS 11. It stores a high-quality photo in roughly half the space of a JPEG by using HEVC compression. The trade-off is compatibility: many Windows programs, older apps, and web uploaders still can’t open a .heic file. Converting to PNG or JPG makes those photos work everywhere without any visible loss of quality. If you’d rather stop the format entirely, see how to turn off HEIC on iPhone.
HEIC vs JPG
HEIC files are about half the size of an equivalent JPG and support extras like transparency and image sequences. JPG, on the other hand, opens in literally every app and device. If storage matters and you stay in Apple’s ecosystem, HEIC wins; if you need to share, edit, or upload a photo anywhere else, JPG (or PNG) is the safer choice. Our HEIC vs JPG guide breaks it down in detail.
PNG vs JPG
PNG is lossless and keeps transparency, so it’s perfect for graphics, logos, text, and anything with sharp edges — but the files are larger. JPG discards a little data to produce much smaller files, which is fine for photographs where a tiny quality loss is invisible. A good rule of thumb: use PNG for graphics and JPG for photos.
WEBP vs PNG, and when to use AVIF
WEBP was designed for the web and typically produces smaller files than PNG while still supporting transparency, which makes it excellent for website images. AVIF goes a step further with even better compression and quality, and is now supported by every major browser. Both are great when page speed matters. For maximum compatibility — email attachments, older software, print — stick with PNG or JPG.
Frequently asked questions
Does Conversion Wizard upload my photos?
No. Every conversion runs entirely in your browser using WebAssembly and your device’s own image tools. Your files are never intentionally sent to or stored on a server.
Is it really free and unlimited?
Yes. There’s no signup, no watermark, and no cap on how many images you convert. Sensible per-batch limits (up to 50 files at once) simply keep your browser responsive.
Can I convert files on my iPhone or Android?
Yes. The converter works in mobile Safari and Chrome. Pick images from your library, convert them on-device, and save the results back to your phone.
Does converting reduce image quality?
Converting to PNG is lossless — no visible quality is lost. For JPG and WEBP you can choose a quality level; 90–95% looks identical to most eyes while keeping files small.
Does it work offline?
Once the page has loaded, conversion happens locally, so it keeps working even with a flaky connection. Nothing needs to reach a server to convert your files.
Is there a file size limit?
You can convert files up to 100 MB each. Because everything runs in your browser, very large images depend on your device’s available memory.
