Frequently Asked Questions

Does PNG to JPG conversion lose quality?

∨
Yes. JPG uses lossy compression, so the conversion reduces quality compared to the original PNG. At quality settings of 85-95%, the visual difference is minimal while file size is dramatically reduced. PNG's lossless quality cannot be recovered once converted to JPG.

Will the file size be smaller after conversion?

∨
Yes, significantly. JPG files are typically 5-10 times smaller than PNG files at comparable quality. This makes JPG ideal for photos, web images, and email attachments where file size matters more than perfect pixel preservation.

What happens to transparency in PNG?

∨
JPG does not support transparency. When converting a PNG with transparent areas to JPG, the transparent regions are filled with white. If you need to preserve transparency, consider converting to WebP instead, which supports both transparency and good compression.

When should I use JPG instead of PNG?

∨
Use JPG for photographs, complex images with many colors, and any image where file size is a priority. JPG's compression is optimized for natural images. Use PNG when you need sharp edges, text, transparency, or lossless quality — like logos, screenshots, and graphics.

Are there any file size limits?

∨
Since all processing happens in your browser, the practical limit depends on your device's available memory. Most images under 50MB work fine. Very large images (100MB+) may cause performance issues on lower-end devices.

Is my image uploaded to a server?

∨
No. All conversion happens entirely in your browser using the HTML5 Canvas API. Your image is never uploaded, stored, or transmitted anywhere.

Can I convert PNG screenshots to JPG?

∨
Yes, but it's not recommended for screenshots with text or UI elements. JPG compression creates artifacts around text, making it harder to read. For screenshots, PNG is usually better. Use JPG for photographic content where smooth gradients matter more than sharp text.

How do I convert PNG to JPG without losing too much quality?

∨
Set the quality slider to 90–95% for near-lossless visual quality while still reducing file size. At this range, the compression artifacts are barely visible to the human eye, but the file size can be 70–90% smaller than the original PNG.

What happens to PNG metadata when converting to JPG?

∨
Basic metadata such as color space information is preserved. However, PNG-specific metadata like gamma values and text chunks are not carried over to JPG. EXIF data from the original image is also not preserved in the conversion.

Can I convert PNG icons to JPG?

∨
Yes, but icons typically look better in PNG format because they contain sharp edges and limited colors. JPG compression blurs sharp edges and introduces noise in solid color areas. For icons, consider WebP if you need smaller files with transparency support.
