JPG is commonly suitable for photographs where a compact file is important and transparency is not required. PNG supports transparency and preserves crisp edges. WebP can provide efficient compression for web imagery, while SVG stores mathematical vectors.
Select formats by purpose
JPG is generally useful for photographs where compact size matters. PNG preserves sharp lines and transparency, which makes it ideal for interface graphics, screenshots, and typography overlays. WebP reduces file size across both photos and illustrations. SVG stores vector shapes and is the best format for logos, glyphs, and iconography.
Avoid unnecessary conversions
Changing formats repeatedly does not automatically improve an image. Re-encoding an already compressed JPG into another format can introduce compression artifacts, while converting a transparent logo to JPG adds an unwanted solid background.
Review the exported file
Check file size, dimensions, transparency, and rendering compatibility. For SVG files, sanitize the source code to ensure untrusted scripts are not embedded. Preserve your vector master files and export optimized delivery assets for the web.
A safe, repeatable tool workflow
- Confirm the expected input and output formats before processing files.
- Keep an untouched original until the result has been opened and checked.
- Test a representative sample, including a larger or unusual file if relevant.
- Check output quality, file size, page order, calculations, and formatting.
- Review privacy information before processing confidential or customer data.
Troubleshooting checklist
If a task fails, verify the file, format, size limits, and browser support. Try a small non-sensitive sample and record the exact error if the issue persists.
