About Image Resizer & Compressor
Use this free online tool to batch-resize and compress JPG, PNG, and WebP photos without uploading them to any server. Everything runs locally in your browser, ensuring your photos remain 100% private. It's the perfect utility for web developers, designers, or anyone needing to reduce image file size for social media, email attachments, or website optimization.
Simply drag and drop up to 15 images into the dropzone. Set your target width and height (choose between "Fit within" to keep proportions, or "Exact size" to stretch). Adjust the quality slider to compress JPEG or WebP files, and watch as your images are processed instantly. Finally, click "Download all as ZIP" to get your optimized images.
Keep "Fit within" enabled and leave "Allow upscale" off to avoid making small photos blurry. If you upload heavy PNG files but don't need transparent backgrounds, switch the output format to JPEG or WebP to drastically reduce the image size. Need more formats (AVIF, GIF, BMP, ICO)? Use the Image Converter.
Frequently Asked Questions
How to reduce image size without losing quality?
To reduce file size while maintaining quality, use our 'Fit within' option to scale down large dimensions, and adjust the Quality slider (for JPEG/WebP) around 80-85%. This strikes the best balance between a small file size and clear image quality.
Is this a free batch image resizer?
Yes, you can batch resize and compress up to 15 images at once for free. Simply drag and drop your photos, set the dimensions, and download them all instantly as a ZIP file.
How do I change a photo to an exact pixel size?
Select 'Exact size' in the Resize Mode settings. Enter your desired width and height, and uncheck the 'Lock aspect ratio' button if you want to stretch or compress the image to those exact pixels.
Are my photos uploaded to a server?
No. All resizing and compression runs entirely in your browser using local processing. Images never leave your device, ensuring 100% privacy and security.
Which image formats are supported?
Our tool supports JPG, PNG, and WebP inputs. You can choose to keep the original format or convert your images between JPEG, PNG, or WebP during the export process. For AVIF, GIF, BMP, or ICO conversions, use our free Image Converter at /tool/image-converter.
Is there a file size limit for uploads?
Yes, each individual image must be 5MB or smaller. This ensures your browser doesn't freeze or crash during the local batch resizing process.
