Crop, resize, rotate and flip your images with precision. All processing happens in your browser — your files never leave your device.
or click to browse your files
Transform your images in three straightforward steps — no software installation needed.
Drag and drop a PNG, JPG, or WEBP file onto the upload area, or click the "Choose Image" button to select a file from your device. The image loads instantly in your browser and never gets sent to any external server, so your photos stay completely private from the moment you open them.
Use the interactive crop box to select the portion of the image you want to keep. Pick a preset aspect ratio such as 1:1 for profile pictures, 4:3 for presentations, or 16:9 for video thumbnails. Enter exact pixel values for width and height to resize with precision. Rotate the image by 90-degree increments or use the free rotation slider for any custom angle. Flip horizontally or vertically with a single click.
When you are satisfied with the preview, click "Apply & Download" to save the final image to your device. The processed file downloads in its original format at the dimensions you specified. There are no watermarks, no branding, and no quality restrictions — your image is ready to share, print, or upload wherever you need it.
A powerful, private, and completely free alternative to desktop image editors.
Every feature of the crop and resize tool is available at no cost. Your output images are clean and unbranded — we never stamp watermarks, logos, or "trial" labels onto your work. Use it as often as you need without hitting any usage cap.
Drag the handles of the crop box directly on your image to frame exactly the area you want. The live preview updates in real time so you can see the result before committing. Choose from popular aspect ratios like 1:1, 4:3, 16:9, and 3:2, or use free-form cropping for full flexibility.
Enter exact width and height in pixels to scale your image to the dimensions you need. Lock the aspect ratio to maintain proportions automatically, or unlock it to stretch and reshape. Whether you need a 1080x1080 Instagram post or a 1920x1080 desktop wallpaper, precise pixel control makes it simple.
Straighten a tilted photo, turn a landscape shot into portrait orientation, or mirror an image for design purposes. Use quick 90-degree rotation presets or the continuous slider for fine angle adjustments from -180 to 180 degrees. Horizontal and vertical flip buttons let you mirror the image instantly.
Your images never leave your device. All cropping, resizing, and rotation happens directly in your browser using the HTML5 Canvas API. There is no upload step, no cloud storage, and no third-party access. When you close the tab, every trace of your work is gone.
The tool runs on any device with a modern browser. Use it on your desktop, laptop, tablet, or smartphone — Chrome, Firefox, Safari, and Edge are all fully supported. There is nothing to download or install, and it works equally well on Windows, macOS, Linux, iOS, and Android.
Practical knowledge to help you get the best results from your images.
Cropping and resizing serve different purposes, and understanding the distinction will help you choose the right approach for each situation. Cropping removes parts of the image that you do not want — it cuts away the edges to focus on a specific area or subject. The remaining portion keeps its original resolution and pixel density, so quality stays high. Resizing, on the other hand, changes the overall dimensions of the entire image without removing any content. When you reduce the size, pixels are combined and the file becomes smaller; when you enlarge, the software interpolates new pixels, which can sometimes introduce softness. A good rule of thumb: crop first to frame your subject, then resize to meet the exact pixel requirements of your destination platform.
Different platforms require different aspect ratios, and using the correct one prevents awkward cropping or black bars when you upload. Instagram feed posts look best at 1:1 (1080x1080 pixels), though the platform also supports 4:5 for taller portrait shots that take up more screen space. Facebook shared images perform well at 16:9 (1200x675) for link previews and 1.91:1 for ad images. Twitter (X) timeline images display at roughly 16:9 or 2:1 depending on the number of images in a post. YouTube thumbnails use 16:9 at 1280x720 pixels. LinkedIn post images work best at 1200x627 (approximately 1.91:1). For print projects, the classic 3:2 ratio matches standard photo print sizes like 4x6 and 6x9 inches. Presentations and slides typically use either 16:9 for widescreen or 4:3 for traditional screens. Knowing these ratios before you crop saves time and ensures your images look sharp on every platform.
Pixel dimensions and DPI (dots per inch) are related but serve different purposes. Pixel dimensions define the total number of pixels in the image — for example, an image that is 3000 pixels wide by 2000 pixels tall. DPI defines how many of those pixels get packed into each physical inch when you print the image. On screen, DPI is largely irrelevant because monitors display images pixel-for-pixel regardless of the DPI metadata. For printing, however, 300 DPI is the standard for sharp, professional output. A 3000x2000 pixel image printed at 300 DPI produces a 10x6.67 inch print. The same image at 72 DPI would produce a much larger but lower-quality print at about 41.7x27.8 inches. When you resize an image for web use, focus on pixel dimensions alone. When preparing images for print, calculate the pixel dimensions you need by multiplying the desired print size in inches by 300.
Every time an image is saved in a lossy format like JPG, some quality is lost. To minimize degradation, avoid repeatedly opening, editing, and saving the same JPG file — each save cycle introduces additional compression artifacts. If you plan to make multiple rounds of edits, consider working with PNG (which is lossless) and converting to JPG only as the final export step. When resizing, always scale down rather than up whenever possible. Enlarging an image forces the software to invent pixels that did not exist in the original, which results in blurriness. If you must enlarge, keep the increase modest — going beyond 150% of the original size usually produces noticeably soft results. For cropping, try to start with the highest-resolution version of the image available. The more pixels you have to begin with, the more room you have to crop tightly while still retaining enough resolution for your intended use.
Sometimes you need to crop an image and then compress it, or resize and then convert it to a different format. ConvertKr offers separate tools for each of these tasks, and they work well together as part of a workflow. For example, you might crop and resize a product photo here, then use the Image Compress tool to reduce its file size for faster web loading, and finally use Image Convert to save it as WEBP for optimal browser performance. Since all tools process locally in your browser, moving between them is fast — just open a new tab and drop your file. For social media content creators who prepare multiple images at different sizes, this approach keeps everything efficient without requiring a heavyweight desktop application.
Common questions about the Image Crop & Resize tool.
Yes, completely. There are no premium tiers, no per-image fees, and no daily usage limits. Every feature — cropping, resizing, rotation, and flipping — is available at no cost. Your output images are never watermarked.
The tool accepts PNG, JPG (JPEG), and WEBP images. When you download the cropped or resized result, it is saved in the same format as the original. All three formats are widely supported across browsers and devices.
Yes. Enter specific width and height values in pixels in the resize controls. Enable "Lock aspect" to maintain the original proportions when you change one dimension, or disable it to set width and height independently for custom proportions.
The tool includes five aspect ratio presets: Free (unconstrained), 1:1 (square), 4:3 (standard), 16:9 (widescreen), and 3:2 (classic photo). Select any preset and the crop box automatically constrains to that ratio as you drag.
Yes. Quick rotation presets let you rotate 90, 180, or 270 degrees with a single click. The free rotation slider supports precise angle adjustments from -180 to 180 degrees. Horizontal and vertical flip buttons mirror the image along either axis.
Your images never leave your browser. All processing — cropping, resizing, rotation, flipping — happens locally using JavaScript and the HTML5 Canvas API. No data is uploaded to any server. When you close the page, all image data is discarded.
There is no hard file size limit enforced by the tool. Since all processing happens in your browser, the practical limit depends on your device's available memory. Most modern devices handle images up to 30-50 MB without issues. Very large files may take a moment to render.
No. The tool works instantly without any signup, login, or account creation. Just open the page, upload your image, make your adjustments, and download the result. There is nothing to register for and no personal information collected.
