Image Format Converter: JPG, PNG, WebP, and SVG Bidirectional
Different image formats are good at different things. JPG compresses photos well; PNG handles transparency and sharp edges; WebP beats both in modern browsers; SVG is the only true vector format. This converter handles all common formats — and now SVG in both directions.
Choosing a format involves trade-offs. JPG is universal and small for photos but can't do transparency. PNG is lossless and supports transparency but bloats photo files. WebP is the modern compromise — smaller than JPG and PNG with transparency support, but slightly less universal. SVG is mathematical (vector) and infinitely scalable but only suits flat graphics.
EllyTools converts between all of these. SVG output uses imagetracerjs to vectorize raster images — best for logos and flat illustrations, not photographs.
Which format for which use
| Use case | Format | Why |
|---|---|---|
| Photos on the web | WebP (or JPG) | Best compression for photographic content |
| Transparency required | PNG or WebP | JPG has no alpha channel |
| Logos / icons / illustrations | SVG | Scales without quality loss |
| Print-quality photos | TIFF or maximum-quality JPG | Compression artifacts visible at print size |
| Email attachments | JPG | Universal compatibility |
Extended FAQ
Does converting JPG → PNG improve quality?
No. The losses already in the JPG stay in the PNG. Conversion can preserve current quality but cannot recover what's been compressed away.
When should I convert PNG to SVG?
Only for clean line art, logos, or icons. Photos vectorize poorly — the result is large, noisy, and no better than a compressed PNG.
Are my images uploaded?
No — runs entirely in your browser.
