Frequently Asked Questions

Do the image tools upload my images to a server?
No. Image compression, resizing, and format conversion all run entirely in your browser using the Canvas API. Your images never leave your device — important when you're processing sensitive screenshots, internal mockups, or client work under NDA.
What's the difference between PNG, JPG, WebP, and AVIF?
PNG: lossless, supports transparency — best for logos, screenshots with text. JPG: lossy, smaller files — best for photos. WebP: modern, ~30% smaller than JPG/PNG with similar quality, supported everywhere now. AVIF: next-gen, ~50% smaller than JPG, but slower to encode and slightly less universal browser support.
Can I use these for accessibility checking?
The HEX/RGB/HSL converter shows WCAG contrast ratios for any color pair — useful for checking text legibility against backgrounds (WCAG AA requires ≥4.5:1 for body text, ≥3:1 for large text).
Will these tools work on slow phones?
Yes. The pages themselves are static and lightweight. Image processing is the slowest task — for very large images (4000×4000+), expect a few seconds on lower-end hardware. Most modern phones handle 1080p images instantly.
Can I generate Tailwind-compatible output?
Yes — the gradient generator outputs both raw CSS and Tailwind utility classes. The color palette generator exports as Tailwind config blocks. The px-to-rem converter (in Developer Tools) shows the Tailwind size scale.
