Add a photo to see print size
About this tool
Image Resizer is a browser-based photo resizer, picture cropper, and image converter built for designers, marketers, developers, and anyone who needs to change image size without installing desktop software. Use it to resize an image to exact pixels, reduce image size for faster pages, crop a photo to 1:1 or 16:9, compress a JPEG, convert PNG to JPG, or export WebP for modern websites. Presets cover Instagram photo size, YouTube thumbnail size, Facebook cover dimensions, LinkedIn banners, Pinterest pins, Open Graph images, favicons, HD frames, and print sizes at 300 DPI.
The workspace supports bulk image resize: add a queue of pictures, apply one set of dimensions, quality, and format rules, then download a ZIP archive. Advanced controls include aspect-ratio lock, contain / cover / stretch fit, rotation and flip, padding, rounded corners, brightness and contrast, saturation, hue, blur, sharpen, grayscale, sepia, text watermark, background flatten, nearest-neighbor or smooth resampling, and a target-kilobyte encoder for JPEG and WebP. A live compare view helps you judge how much detail a compress-image pass removes.

No Data Collection: All image processing, resizing, and conversion occurs strictly locally within your web browser. We do not upload, store, monitor, or transmit your images to any external servers. Consequently, you retain sole responsibility for the copyright status, legality, and privacy of all content you process.
Limitation of Liability: In no event shall the authors, creators, or hosting providers be liable for any claim, damages (including but not limited to direct, indirect, incidental, special, or consequential damages), data loss, financial loss, legal disputes, print-shop refusals, or other liability, whether in an action of contract, tort, or otherwise, arising from, out of, or in connection with the use of this software. By using this tool, you expressly agree that you use it entirely at your own risk and must independently verify the accuracy and quality of all exports before use.
You are solely responsible for the files you process. Do not upload or transform content you do not have the right to modify. Keep original masters; canvas re-encoding strips most embedded metadata and cannot be reversed. Always verify width, height, orientation, color, transparency, and file weight in an independent viewer before commercial, legal, medical, archival, or print use. Nothing on this page constitutes professional advice.
FAQ
Answers cover how to resize a picture, compress photos, and convert formats. Confirm every export yourself.
The tool decodes your photo in the browser, then redraws it onto an HTML canvas at the width, height, or percentage you specify. You can resize an image by exact pixels, scale by percent, fit within a maximum box, or apply a social-media preset such as an Instagram post, YouTube thumbnail, or Open Graph image. Cropping, rotation, color adjustments, and format conversion happen in the same pass. Because every browser, color profile, and source file is different, you must open the exported file and confirm that the pixel dimensions, orientation, and visual quality match your intended use before publishing or printing.
