Websites want PNG, social apps want JPG, page speed prefers WebP, and iPhone photos come out as HEIC... Image formats are a mess, and you often hit "wrong format, can't use". An online image converter solves it: no Photoshop, open a page and convert images to whatever format you need.
This guide covers online conversion and how to pick the right format.
Common formats at a glance
- JPG: most compatible, ideal for photos, moderate file size
- PNG: supports transparency — for logos and screenshots
- WebP: small size, high quality — the modern web format
- HEIC: iPhone default, poor compatibility, needs conversion
- SVG: vector, scales without blur — for icons
Understand the difference, and you'll know what to convert to.
Steps to convert online
Use the PixelForge Image Format Converter:
- Upload your image
- Pick the target format (JPG, PNG, WebP, etc.)
- Click convert
- Download the result
Everything runs in the browser — images never leave your device.
Pick the format by scenario
Web images → WebP
WebP is 30%-50% smaller than JPG with near-identical quality. Batch-convert large images to WebP and pages load much faster.
Transparent backgrounds → PNG
Logos, icons and stickers need transparency — that requires PNG. JPG doesn't support it, so choose PNG when converting.
General sharing → JPG
JPG is the most compatible for sending and uploading anywhere. Convert WebP, HEIC and large PNGs to JPG for maximum compatibility.
iPhone → HEIC to JPG
HEIC photos from iPhones often won't open on computers or WeChat. Convert to JPG or PNG for normal use.
Convert + compress combo
Some conversions inflate size, or the result is still too big. After converting, use the online compressor to control size:
- Convert to the needed format first
- Compress to control volume
- Get compatibility + small file size
