PNG vs JPG: Which Image Format Should You Use?
Both formats are everywhere, but they serve different purposes. A practical comparison for web, print, and storage.
PNG and JPG are the two most common image formats on the internet. Choosing the wrong one wastes bandwidth, loses quality, or breaks transparency.
When to Use JPG
JPG uses lossy compression, producing small files ideal for photographs, web galleries, and email attachments. It does not support transparency.
When to Use PNG
PNG uses lossless compression and supports full transparency. Use it for logos, icons, screenshots with text, and graphics with sharp edges.
Pro tip: For web photos, JPG at 80-85% quality usually beats PNG on file size with no visible difference.
Conversion Tools
Convert between formats with our PNG to JPG and JPG to PNG tools. For further size reduction, run output through the Image Compressor.
Modern Alternative: WEBP
WEBP offers smaller files than both PNG and JPG. When compatibility allows, consider WEBP. When it does not, stick with JPG for photos and PNG for graphics.
Real-World File Size Comparison
A typical 4000x3000 photo might be 8 MB as PNG, 2 MB as high-quality JPG, and 1.5 MB as WEBP. Logos with transparency stay smallest as PNG when quality matters more than size.
Key Takeaways
- JPG for photographs and web galleries
- PNG for logos, screenshots, and transparency
- Convert format before compressing for best results
A third option for websites
Use PNG to JPG for a photo that does not need transparency. Keep PNG for logos and screenshots. On a website in 2026, PNG to WEBP is often the smaller file that still allows a transparent background, as long as you are not sending it to a printer.
Make the choice once
Logos and screenshots stay PNG. Photographs that must be small and universal become JPG, once, from the PNG or the camera file. A website in 2026 can also take WEBP, including a transparent graphic, as long as you are not handing the file to a printer that has never heard of it. Do not bounce PNG to JPG and back. The return trip does not restore the transparency or the detail.
If you are unsure, look at the edges. Hard edges, text, and flat color want PNG. Soft photographs want JPG when file size matters. A screenshot of a photo is still a screenshot. If it contains labels, prefer PNG so the labels stay sharp. Transparency is the other test. If you can see a checkerboard or a logo with no box, JPG will paint a box. WEBP can keep transparency for the web. Print shops usually still say JPG or TIFF, and you should ask them.
Keep the editable or lossless master, and export the delivery file from it. For a logo that is SVG, export PNG for slides and a JPG only if a form refuses PNG. For a photograph, the camera original or a lightly edited TIFF or PNG is the master, and JPG is the delivery file. WEBP can be the web delivery file in 2026. Write those roles in the file name. Future you will not remember which bounce was the clean one, and the pixels will not tell you after two lossy saves.
When a template says upload a logo, ask if the background must be transparent. If yes, PNG or WEBP. If the template flattens everything onto a colored header, JPG can be fine and smaller. Look at the preview the template shows after upload. A white box around a logo means you sent JPG or a PNG with a white background you did not notice. Fix the master, export again, and replace the file. Do not trace the box by hand.
When both files exist, the larger one is not automatically the better master. A large JPG can be worse than a smaller PNG of a logo.
