Image Compress
You can reduce image file sizes directly in your browser with Image Compress, ensuring nothing ever touches a remote server. Simply upload your PNG, JPG, WEBP, GIF, or BMP files, tweak the quality slider to your liking, and grab your optimized results in just a few seconds. The workspace combines five essential tools in one place: you can compress, resize, crop, convert, and rotate images without switching tabs. Whether you need to adjust compression levels or set exact pixel dimensions, every mode provides the precise control you need for professional results. The side-by-side preview lets you compare the original against the processed version, showing exact byte savings so you know the impact of your changes before you hit download.
Compress
Reduce image file size with adjustable quality for JPEG, WEBP, and PNG output formats.
Resize
Change image dimensions with aspect ratio lock and quick presets for common sizes.
Crop
Cut images to exact regions with offset controls and aspect ratio presets like 1:1 and 16:9.
Convert
Switch image formats between JPEG, PNG, and WEBP with quality control during conversion.
Rotate
Rotate images by 90, 180, or 270 degrees and flip horizontally or vertically.
Online Image Compress with Side-by-Side Preview
Seeing the difference between original and compressed images matters when optimizing for the web. The interface displays both versions side-by-side on one canvas, complete with file size and dimension labels to help you compare results instantly. The percentage savings badge makes it immediately clear how much smaller your output file is. Drag and drop any image onto the workspace or click the upload button to get started. Results appear instantly as you adjust the quality slider, so there is no waiting for a server round-trip.
Adjustable Quality for JPEG and WEBP
The quality slider ranges from 1 to 100 and directly controls the compression level for JPEG and WEBP output. Lower values produce dramatically smaller files at the cost of visual fidelity. For most photographs, values between 70 and 85 deliver excellent results with minimal visible artifacts. PNG output is lossless and does not use the quality slider.
Drag and Drop or Click to Upload
Getting images into the workspace takes just one action. You can drag files directly from your desktop or file manager onto the preview panel, or simply click the upload button to browse your file system. You can upload and process various formats, including PNG, JPG, WEBP, GIF, BMP, and SVG.
Resize, Crop, and Convert Images in One Workspace
In addition to compression, four more modes cover all your standard image editing needs in one place. Resize lets you change pixel dimensions with aspect ratio lock or choose from presets like 50%, 800px, and 1920px width. Crop trims images to exact regions using X/Y offsets and width/height controls, with quick buttons for popular aspect ratios. Convert switches between JPEG, PNG, and WEBP formats in one click. Rotate offers four fixed angles and horizontal or vertical flip, so correcting image orientation takes seconds.
Aspect Ratio Presets for Social Media and Web
Quick preset buttons for 1:1, 16:9, 4:3, and 3:2 aspect ratios make it straightforward to prepare images for Instagram squares, YouTube thumbnails, website banners, and print layouts. Click a preset, adjust the offset to frame your subject, and download the cropped result.
Format Conversion with Quality Control
Switching from PNG to JPEG or WEBP often reduces file size by 60-90% for photographs. You get the same granular quality slider in convert mode as you do in compress mode, giving you complete control over the balance between file size and image clarity during format conversion.
Free Image Compress for Developers, Designers, and Content Creators
Optimizing images before uploading to websites, apps, or social media platforms saves bandwidth, speeds up page loads, and improves user experience. The compressor handles everything right inside your browser, meaning there is nothing to install, no account required, and no limits on file size. Every operation runs client-side using the HTML Canvas API, so your photos, screenshots, and design assets never touch a remote server. Downloads come without watermarks, branding, or premium tier restrictions.
No Signup, No Limits, No Server Uploads
All five processing modes, file upload, drag-and-drop, and download are available immediately with zero registration. There are no daily caps on how many images you can process. Your session data exists only in browser memory and disappears when you close the tab.
Client-Side Processing for Complete Privacy
Every pixel operation happens inside your browser. Your images never travel across the network, making this a safe choice for confidential screenshots, proprietary design files, and personal photographs. The entire system is designed with privacy at its core, ensuring your personal data stays on your device where it belongs.
