To compress image files online without losing noticeable quality, upload your JPG, PNG, or WebP file and select the Recommended (80%) preset or convert to modern WebP format. Our image compressor runs 100% inside your web browser using HTML5 Canvas and native WebAssembly graphics APIs. When you drop an image, the browser decodes the bitmap, resamples the pixel matrix, and re-encodes the image into your chosen format. Your files never leave your device or travel across any remote network.

Lossy compression (such as JPEG and standard WebP) discards high-frequency pixel variations that are imperceptible to human vision, drastically reducing file size by 50% to 85% with virtually zero perceptible degradation at the Recommended (80%) preset. If you require bit-for-bit lossless pixel preservation, use the PNG target format or select the Lossless preset (100%).

WebP is a modern web image format developed by Google that delivers 25% to 35% smaller file sizes compared to JPEG at equivalent visual quality. It supports both lossy and lossless compression as well as 8-bit alpha transparency, making it the ideal standard for boosting Google Core Web Vitals and PageSpeed scores.

Yes! Use the Scale & Maximum Dimensions controls to downscale your images by 75%, 50%, or 25%, or specify optional maximum width and height pixel boundaries. Resizing high-resolution camera photos (e.g. 4000x3000px) down to web dimensions (e.g. 1920x1080px) yields dramatic 90%+ bandwidth savings.

Because all encoding takes place in client-side RAM using your device's GPU/CPU capabilities, you can compress images up to 50MB with zero daily quotas, zero watermarks, and no sign-up or registration required.

Image Compressor features 16 desktop productivity hotkeys across 3 categories. In Navigation & Studio: press / to open file picker, Alt+V to toggle Studio (2-Column) vs Stacked view, Alt+D to star favorite tool bookmark, Alt+K (or ?) for shortcuts guide, and Esc to dismiss modals or reset workspace. In Image & Controls: press Alt+P for DevToys Smart Clipboard auto-detect, Ctrl+Enter to download, Alt+S for developer code snippets, Alt+R for benchmark scenarios, and Ctrl+V to paste. In Quick Formats & Export: use Alt+1 (WebP 80%), Alt+2 (WebP 50%), Alt+3 (JPEG 80%), Alt+4 (PNG 100%), Alt+5 (50% scale), and Alt+6 (copy image blob).

Yes! Click the 'Copy Image' button to write the processed image directly to your system clipboard as a PNG blob. You can then paste (Cmd/Ctrl+V) it straight into Slack, Discord, Figma, Photoshop, Notion, or email clients.

Use our interactive Visual Studio with 3 preview modes: Curtain Splitter (drag the split divider handle in real time), Side-by-Side (independent side-by-side comparison panes), and Output Only. You can also zoom from 50% to 200% to inspect subpixel compression artifacts and color fidelity.

Yes! You can define a custom output file base name in the Output Filename Customization panel. Toggling 'Append Today\'s Date' appends the current date stamp (_YYYY-MM-DD) for organized, chronological asset archiving.

Click the 'API Code' button in the toolbar (or press Alt+S) to view and download ready-to-use scripts in JavaScript (HTML5 Canvas & FileReader), HTML5 (<picture> markup), Node.js (Sharp), Python (Pillow / PIL), and Go.
