Image Resize Tool
Adjust your image dimensions, crop to exact regions, or rotate with precision using our all-in-one browser editor. Drag in your PNG, JPG, WEBP, GIF, or BMP files to set target sizes in pixels or percentages, then lock the aspect ratio to maintain proportions and download your results instantly. Our workspace combines five powerful editing modes: Resize, Crop, Rotate, Flip, and Compress. Since everything happens locally via the Canvas API, your photos never leave your device or touch a remote server.
Resize
Set exact pixel dimensions or scale by percentage with aspect ratio lock and common size presets.
Crop
Trim images to precise rectangular regions using pixel coordinates or aspect ratio presets like 1:1, 16:9, and 4:3.
Rotate
Turn images by any angle from -180 to 180 degrees with automatic canvas expansion.
Flip
Mirror images horizontally, vertically, or both for reflections and orientation corrections.
Compress
Reduce file size by choosing JPEG, WebP, or PNG format and adjusting the quality slider.
Free Image Resize Tool with Presets and Aspect Ratio Lock
Start by dropping your image directly onto the workspace or using the quick upload button. Once you've loaded a file, the left panel provides intuitive controls for your current editing mode, while the right panel reflects every change in a live preview. Use the status bar at the bottom to stay informed about original dimensions, the active mode, and your file name.
Pixel and Percentage Resizing
Fine-tune your output by entering exact pixel dimensions or switching to percentage mode for proportional scaling. You can lock the aspect ratio to ensure both dimensions update together, preventing unwanted distortion. For common requirements, just click a preset like 1920x1080 for HD, 1280x720 for web, or 256x256 for icons.
Crop with Aspect Ratio Presets
Precision cropping is simple: just enter your X and Y offsets along with target width and height. You'll also find standard aspect ratio presets like 1:1 (square), 16:9, and 4:3 that update the crop area instantly. These tools make it easy to prepare content for Instagram, YouTube thumbnails, or mobile stories.
Rotate, Flip, and Compress Images in One Workspace
In addition to resizing, you can explore specialized modes for rotating, mirroring, and optimizing file sizes. The rotation tool supports any angle between -180 and 180 degrees, complete with automatic canvas expansion so you never lose your corners. Use the flip mode to mirror images horizontally or vertically, ideal for fixing orientation or creating symmetrical designs, and try the compression mode to balance visual quality with file size in JPEG, WebP, or PNG formats.
Reduce File Size Without Visible Quality Loss
Adjust the quality slider to find the perfect balance for your needs; settings between 80% and 90% often reduce file size by 50-80% with no noticeable loss in clarity. WebP is particularly effective at creating lightweight images that are perfect for modern web and social media workflows.
Drag and Drop or Click to Upload
Getting your images into the editor is straightforward: use the upload button, drag files into the preview area, or use the central drop zone. All common formats are accepted, including PNG, JPG, WEBP, GIF, BMP, and SVG.
