Free Browser-Based Image Editing and Color Tools

Every tool in this hub runs entirely in your browser. Images are processed locally with JavaScript and the HTML5 Canvas API — your photos are never uploaded to a server, which means faster processing, full privacy, and no file size limits imposed by an upload pipeline. Simply open a tool, drop in your image, and see results instantly.

The Image Compressor reduces JPEG, PNG, and WebP file sizes with a live quality slider — quality settings between roughly 60 and 85 usually cut file size dramatically with little visible difference. For choosing formats: JPEG is the space-efficient choice for photographs, PNG preserves sharp edges and transparency for screenshots and logos, and WebP typically beats both at the same visual quality. The Image Editor handles resizing, cropping, rotation, brightness/contrast adjustments, and filters; the color tools cover picking colors from images (Image Color Picker), converting between HEX, RGB, and HSL (Color Picker), building accessible color schemes (Palette Generator), and generating CSS code (Gradient and Box Shadow generators). The Color Contrast Checker tests text/background combinations against WCAG contrast ratios: 4.5:1 for normal text and 3:1 for large text under AA, and 7:1 for normal text under AAA.

Image Tools FAQ

Are my images uploaded to a server?
No. All processing — compression, resizing, color picking, conversion — happens locally in your browser using the Canvas API. Your files never leave your device, so sensitive screenshots and photos stay private, and there is no upload wait or size limit.
Should I use JPEG, PNG, or WebP?
Use JPEG for photographs (small files, no transparency support). Use PNG for screenshots, logos, and any image with sharp edges or transparency (lossless, larger files). WebP usually produces the smallest files at equivalent quality and supports transparency — a good default for the web, supported by all modern browsers.
What does lossless vs lossy compression mean?
Lossy compression (JPEG, WebP at typical settings) permanently discards image detail the eye is unlikely to miss, achieving much smaller files. Lossless compression (PNG, GIF) reconstructs the original pixels exactly — required for screenshots with text, line art, and images you plan to re-edit.
What quality setting should I use when compressing JPEGs?
There is no universal answer, but quality levels between 60 and 85 are the usual sweet spot: below ~50 artifacts become visible around edges and text, while above ~90 file size grows quickly for imperceptible gains. Try 80 first, check the preview, and step down until you notice degradation.
What WCAG contrast ratio do I need?
Under WCAG 2.1 AA, normal body text needs a contrast ratio of at least 4.5:1 against its background, and large text (18pt/24px regular or 14pt/18.5px bold and up) needs 3:1. The stricter AAA level requires 7:1 for normal text and 4.5:1 for large text. UI components and graphical objects need 3:1.
How do I find the exact color code from a photo?
Use the Image Color Picker: upload or drop any image, hover to see a magnified pixel preview, and click to capture the exact color as HEX, RGB, and HSL values, ready to copy into CSS or a design tool.
