Frequently Asked Questions
What's the best image format for websites? +
WebP is the best choice for web in 2025 — 25-35% smaller than JPG at equal quality, with full browser support. Use PNG for transparency. Use SVG for logos/icons. AVIF is better than WebP but browser support is still growing.
Does converting PNG to JPG lose quality? +
Yes. JPG uses lossy compression — you lose some quality on every save. The quality parameter controls the trade-off (80-90% is usually the sweet spot). PNG is lossless. Converting JPG to PNG does NOT restore the quality already lost in the original JPG.
How do I convert images to WebP for faster loading? +
Convert your JPG/PNG images to WebP using this tool. Then use the HTML <picture> element with WebP as primary and JPG/PNG as fallback: <picture><source srcset="img.webp" type="image/webp"><img src="img.jpg"></picture>
What is the difference between PNG-8 and PNG-24? +
PNG-8 supports 256 colors (good for simple graphics, icons). PNG-24 supports 16.7 million colors (good for photos, complex images). PNG-32 adds an alpha channel for transparency. For photos, JPG or WebP is usually a better choice than either.
Is my image uploaded to a server when I convert it? +
No. All conversion runs in your browser using HTML5 Canvas API. Your image never leaves your device. This makes it safe for converting sensitive or confidential images.
