Convert between PNG, JPG and WebP instantly
PNG, JPG, WebP: Switch Formats in One Click
Form says 'JPG only'? Drag, pick, download — done.
Every format has a job: PNG for transparency and crisp screenshots, JPG for universal compatibility and small photos, WebP as the modern web's most efficient format. The problem is your file isn't always in the format required — the application form only takes JPG, your website wants WebP, the designer expects transparent PNG. This converter switches between all three with one click: drag your image in, click the target format, download. Conversion happens entirely in your browser; your file is never uploaded to a server. When converting transparent images to JPG, transparent areas are automatically placed on a white background; PNG and WebP targets preserve transparency exactly.

Format Choice Guide
Which format for what?
- PNG: transparency, logos, screenshots, lossless
- JPG: photos, universal compatibility, small size
- WebP: most efficient for the web — ~25-30% smaller at equal quality
- Rule of thumb: photo → JPG/WebP, graphics/logo → PNG
Conversion notes
- PNG → JPG: transparent areas turn white, size drops sharply
- JPG → PNG: size GROWS, quality doesn't improve (loss is permanent)
- Anything → WebP: usually the smallest file
- Converting lossy to lossless never restores lost detail
Frequently Asked Questions
Is my file uploaded to a server?
No. Conversion runs entirely on your device via the browser's canvas technology; your image is never sent over the internet. Sensitive files like ID photos are safe to convert.
What happens to transparency when converting PNG to JPG?
JPG doesn't support transparency, so transparent areas are automatically placed on a white background. If you need to keep transparency, choose PNG or WebP as the target.
Does converting JPG to PNG improve quality?
No — detail lost to JPG compression never comes back; the file just gets bigger. JPG → PNG only makes sense when a form or system demands PNG, not for quality.
Why is WebP so praised?
At the same visible quality it produces files ~25-30% smaller than JPG and much smaller than PNG, while also supporting transparency. All modern browsers open WebP; its only weakness is some older software.
Can I convert HEIC (iPhone) files?
If your browser can open HEIC (Safari usually can), conversion works; other browsers may not support it. On iPhone, Settings → Camera → Formats → 'Most Compatible' shoots straight to JPG.
Is there quality loss in conversion?
The PNG target is lossless. JPG and WebP targets use 92% quality — a compression too light to notice. To control the size-quality balance yourself, use our Image Compressor.
