Different image formats are optimized for different jobs. JPEG is ideal for photographs with millions of gradients. PNG preserves hard edges and transparency for logos and UI assets. WebP and AVIF offer modern compression that reduces file sizes by 25-50% compared to JPEG, directly improving web performance scores.
Choosing the wrong format costs you. A PNG screenshot sent in an email is often 10x larger than it needs to be. A JPEG logo loses its crisp edges. A JPEG served on a website loads slower than an equivalent WebP. Matching your image format to its purpose is one of the highest-leverage optimizations available.
With all 13 conversion tools running in your browser, you can convert any image instantly without installing software or uploading files to a third-party server. Your images stay private on your device throughout.
How to convert images
Every converter follows the same simple three-step process.
Tips for better conversions
Always archive the highest quality source file. Conversions are lossy operations and you cannot recover quality once it is gone.
WebP files are 25-35% smaller than JPEG at the same visual quality. Switch to WebP for any image served on a website.
Only PNG and WebP support true transparency. Use PNG when you need a transparent background for logos or UI assets.
AVIF is the newest format with the best compression, but browser support is slightly narrower. Use it alongside a WebP fallback.
For JPEG and WebP, quality settings of 80-85 are visually indistinguishable from higher settings but produce noticeably smaller files.
SVG files are infinitely scalable and tiny. Use them for logos, icons, and illustrations rather than rasterizing to PNG unless a raster format is required.
