Image Converter Online
Image formats split into two families that solve different problems — lossy formats trade detail for small files, lossless ones keep every pixel — and this page covers the whole stack from JPEG to AVIF.

About this converter
Nine image formats live under this hub, and they split into two genuinely different jobs. JPEG, WebP and AVIF are lossy: they analyse what the eye is unlikely to notice and discard it, buying a much smaller file for a small, usually invisible cost in fidelity. PNG, BMP and TIFF are lossless: every pixel that goes in comes back out unchanged, which is the right guarantee for screenshots, logos and anything with hard edges or flat colour that a lossy codec would smear.
A second axis, separate from compression, is metadata and structure. A photo carries EXIF data — the camera model, exposure settings, an orientation flag that tells the viewer which way is up, sometimes GPS coordinates — and converting between formats can keep, strip or mishandle it depending on the tool. HEIC photos from an iPhone also bundle a depth map and edit history inside the same file, which a simple format swap to JPEG or PNG deliberately throws away in favour of a single flat image.
The practical decision usually comes down to destination rather than taste. Uploading to a form that only accepts JPG or PNG, opening a HEIC on a Windows machine that never bought the codec extension, or needing a favicon in the one container browsers actually request — each of those is a compatibility problem, not a quality one, and converting the file is the entire fix.
Frequently asked questions
- Which image format should I use for the web?
- WebP or AVIF for the smallest files at good quality — both are supported by every current browser. JPEG remains the safest fallback for maximum compatibility with older tools and email clients. Use PNG only when you need transparency or the image has sharp edges and flat colour, like a screenshot or logo.
- Why does converting HEIC to JPEG make the file bigger?
- HEIC uses the HEVC video codec, a generation more efficient than JPEG's block-based compression, so the same visual quality costs fewer bytes. Converting to JPEG re-encodes with an older, less efficient method, and the file typically grows by 30-70% even though nothing new was added.
- Will converting my photo lose quality?
- Converting between two lossy formats (JPEG to WebP, for example) re-encodes the image and adds a small amount of generation loss, usually invisible at normal quality settings. Converting to or between lossless formats like PNG, BMP and TIFF keeps every pixel exactly, since nothing is discarded either way.
- Does conversion keep my photo's orientation and metadata?
- Camera photos store an EXIF orientation tag rather than physically rotating the pixels, and most converters read that tag correctly and output an upright image. Full EXIF data — camera model, settings, GPS — is preserved by some tools and stripped by others; check the specific converter if that metadata matters to you.
- What is the difference between lossy and lossless image formats?
- Lossy formats (JPEG, WebP, AVIF) discard detail the eye is unlikely to notice to shrink the file, and repeated re-encoding compounds that loss. Lossless formats (PNG, BMP, TIFF) reproduce every pixel exactly, at the cost of a larger file, with no degradation no matter how many times you open and save.
- Can I batch-convert many images at once?
- Yes — upload multiple files and each is converted to the chosen output format independently, then delivered together. This is the normal way to migrate an entire photo folder from HEIC to JPEG, or to prepare a batch of PNG screenshots as WebP for a website.
