A free suite of browser-based tools for designers and developers, built with care by Trioni.
Palettly is a growing collection of free, browser-based tools for designers and developers. From extracting color palettes from images to converting file formats, generating CSS gradients and compressing images — everything runs directly in your browser.
No sign-up. No backend. No files uploaded to any server. Your data stays on your device at all times. Every tool is free and will remain free forever.
We believe the best tools are the ones that get out of your way. Palettly is designed to be fast, focused and honest — no dark patterns, no invasive ads, no tracking beyond standard analytics.
Palettly is a product of Trioni, a web development and apps studio focused on building useful things for the internet.
Web development and apps studio. We build websites, web applications and digital products. Palettly is one of our open tools — part of our commitment to giving back to the design and developer community.
trioni.netCurrently Palettly includes 13 tools and we're adding more regularly.
Every tool on Palettly follows three principles: it must run entirely in the browser (no server-side processing), it must be genuinely useful (not just another clone), and it must be honest with users (no dark patterns, no hidden costs).
We fund the site through non-intrusive Google AdSense ads and optional donations via Ko-fi and PayPal. We never sell user data, track individual users beyond anonymous analytics, or require registration of any kind.
