The right web image format depends on transparency, detail, browser support, and how aggressively the image must load.

Raster vs. vector: choose by how the artwork must scale

Pixels describe samples; vectors describe shapes. The correct choice follows the content, not a design trend.

Resolution, PPI, and DPI without the myths

Pixel dimensions determine digital detail; print density determines how tightly those pixels are placed on paper.

Why color changes after image conversion

A missing or mishandled ICC profile can shift color even when every pixel value survives.

How to approach images & graphics

Judge an image by content type, target dimensions, transparency, color space, and whether future editing matters.

Image conversion starts with the artwork, not the popularity of an extension. Photographs, interface graphics, logos, scans, and print files need different combinations of pixel resolution, vector structure, transparency, animation, and color metadata. Keep an editable or lossless source, export at the final dimensions, and inspect the result in the browser, device, or print workflow that will use it.

Apply these guides with the image format converter, the SVG vector converter or the image resizer.

Pixels, paths, alpha, and color

Inspect pixel dimensions and embedded color profile. Separate photographic detail from flat graphic regions.

Match the image format to the artwork

Export at the final display or print requirement. Compare edges, gradients, transparency, and metadata.

Image export inspection

  • Pixel dimensions meet the destination requirement.
  • Transparency and edge pixels render correctly.
  • The intended ICC color profile is embedded or converted deliberately.
  • Text, gradients, and fine texture survive at normal viewing size.
