PNG vs JPG vs WebP: which image format to use, and how to convert safely
If your image looks blurry, huge, or has a broken background, it is often a format mismatch.
Start here:
- Converting a transparent PNG? Use PNG to WebP or keep it as PNG.
- Converting a photo? Use JPG to WebP or JPG.
- Need the fastest fix? Try PNG to JPG, and watch for transparency.
Quick comparison
| Format | Best for | Strengths | Trade-offs |
|---|---|---|---|
| JPG | photos | small files; widely supported | no transparency; compression artifacts |
| PNG | logos, UI, screenshots | crisp edges; transparency | larger files for photos |
| WebP | web delivery | small files; transparency support | older apps may not support it |
When PNG is the right choice
Pick PNG when you need:
- transparency (logos, overlays)
- sharp edges (icons, UI)
- lossless screenshots
If you convert a transparent PNG to JPG, the transparency will be replaced with a solid background (often white).
When JPG is the right choice
Pick JPG for:
- photos
- gradients and soft shading
- smaller file sizes with acceptable quality loss
JPG is not ideal for sharp UI elements; you will see halos and blocky edges.
When WebP is the right choice
WebP is a strong default for websites because it can be smaller than JPG and PNG while keeping good quality. It also supports transparency.
If you are sharing files with someone who uses older tools, confirm they can open WebP, or export a JPG/PNG copy.
Quick export checklist
- Do you need transparency? If yes, avoid JPG.
- Is the subject a photo? Start with JPG or WebP.
- Is the target channel performance-sensitive (web/mobile)? Prefer WebP, then JPG.
- Are you sending to an unknown toolchain? Provide a PNG/JPG fallback.
How to convert with Textavia (and avoid surprises)
- Pick the conversion tool you need:
- Upload the image, choose quality if available, then convert.
- Download the output and spot-check it:
- Are edges crisp?
- Did transparency survive?
- Is the file size what you expected?
Two common workflows
- Web banner: Start with JPG → convert to WebP for production; keep PNG only if you need sharp overlays.
- Logo with transparency: Keep a master PNG → export WebP for web → offer a PNG fallback for editors that do not support WebP.
Simple QA before you ship images
- Zoom to 100% and 200%: check edges for halos and banding.
- Toggle dark/light backgrounds behind transparent assets to confirm there is no unwanted fringe.
- Compare file sizes after conversion; if WebP is not smaller than JPG, lower quality slightly and retry.
- Test on mobile and desktop; some low-end devices show banding sooner than high-end monitors.
Common errors
My background turned white
You converted a transparent PNG into JPG. JPG does not support transparency. Use PNG or WebP if you need a transparent background.
The tool says the file is too big
Textavia enforces size and dimension caps to keep conversions safe and fast. Resize the image before converting, or export a smaller version.
The converted photo looks worse than expected
Increase the quality setting, or switch to WebP for better quality at smaller sizes.
FAQs
Will browsers prefer WebP automatically?
Most modern browsers support WebP. Serve WebP first with a PNG/JPG fallback if you need to support legacy clients.
What quality should I pick?
Start around 80 for JPG/WebP. If banding appears, raise it; if files are too large, lower it a bit.
Can I batch-convert here?
The current tools handle one file at a time; for batches, script cwebp/imagemagick locally and use Textavia for quick checks.

Privacy and security
Textavia converts images through a server endpoint on this site, then returns the converted file. Conversions are limited in size and dimensions, and files are not saved as permanent uploads.
