JPEG vs PNG in Showit — which format should you use

Quick answer

Use JPEG for photos, background images, and most standard website imagery. Only use PNG when you need a transparent background — for logos or certain graphics. Showit compresses JPEGs automatically but does not properly compress PNGs, so PNGs can make your site much slower.

How to fix it in Showit

1. Use JPEG for photos, background images, and most standard website imagery

2. Only use PNG when you need a transparent background — for logos, icons, or certain graphics

3. Use SVG for logos and simple graphics where possible — they are vector-based, lightweight, and scalable

4. Currently Showit does not properly support WebP uploads — stick to JPEG, PNG, and SVG

5. FastaSEO will flag images that are in a non-optimal format and identify which ones can safely be converted to JPEG

6. To convert a PNG to JPEG: open the image in any photo editor or use an online converter, save as JPEG, then re-upload into Showit

What's the issue

Showit automatically compresses JPEG images when they are uploaded. However, Showit does not properly compress PNG files — which means PNGs can become unnecessarily large and slow down your website. FastaSEO automatically detects whether an image should remain a PNG or be converted to JPEG, removing a lot of the guesswork.

Why it matters

• Large image files are one of the most common causes of slow Showit sites. Because Showit does not compress PNGs properly, a PNG photo that could be a fraction of the size as a JPEG ends up being served at full weight — slowing down your page for every visitor. Using JPEG for photos and PNG only where transparency is genuinely needed keeps your site fast and your images appropriately sized.

What good looks like

Photos and background images are saved as JPEG. Logos and graphics that need a transparent background are saved as PNG or SVG. No PNG files are used for standard photos where a JPEG would work.
