Choose the format for the image

A photograph, transparent logo and text-heavy screenshot have different requirements. JPG is a practical option for photographs where transparency is unnecessary. PNG can preserve transparency and sharp graphic detail, but large photographic PNGs can be heavy. WebP supports efficient web delivery and transparency; verify compatibility with the platform receiving the file instead of converting everything to one format.

Resize before chasing a smaller quality number

Check the largest rendered size you actually need. Uploading an enormous source image for a small card wastes transfer and decoding work. Preserve the aspect ratio and compare the image at its display size. Higher-density versions can be useful on sharp screens, but they should be deliberate. A converter cannot restore detail that was absent from the original.

Handle transparency deliberately

JPG does not support a transparent background. When converting a transparent asset to JPG, choose a suitable solid background so transparent areas do not become an unintended colour. For logos placed on changing backgrounds, use an appropriate transparency-supporting format. Always open the downloaded output against both light and dark backgrounds if edge quality is important.

Compression is a visual decision

Keep an original copy, reduce dimensions if needed and then adjust quality gradually. Compare edges, fine text, faces and gradients rather than looking only at a percentage saving. File-size savings vary by source; no setting guarantees the same result for every image. Repeated lossy conversions can degrade the image, so return to the original when preparing a different output.

Know browser-tool limitations

Our converter uses browser capabilities and implemented encoders. Available outputs depend on format support; converting an animated input may produce a single frame. Complex TIFF files, colour profiles and unusual camera formats may not behave like a specialised desktop editor. AVIF output depends on browser encoder support. Review orientation, colour, animation and transparency after export.

Use a repeatable website workflow

Name the file descriptively, export a suitable size, inspect the result and upload it to the intended page. Provide informative alt text for meaningful images and explicit dimensions where appropriate to reduce unexpected layout movement. Load below-the-fold imagery lazily, but avoid delaying the main image required for the first screen. Test on a real mobile connection when possible.

Try the tools without replacing your originals

Use the image converter for format or size changes and the compressor for a lighter export. Inputs are processed in your browser by the tools; submitting a project inquiry is a separate action. A large batch can still consume device memory. Start with one representative file, verify the downloaded result and then apply settings to the rest.
