How to Bulk Resize Images Online Free — Step by Step

  1. Upload your images. Drag and drop up to 50 images into the upload area, or click to browse. You can add more images after the first upload if you need to. The tool accepts JPG, PNG, and WEBP files.
  2. Set your target dimensions. Choose between pixel or percentage mode. Enter your desired width and height, and keep the aspect ratio locked so your images stay proportional. You can also override dimensions for individual images in the table.
  3. Choose format and quality. Pick an output format (keep original, JPG, PNG, or WEBP) and adjust the quality slider. A value between 75–85% gives good results for most uses.
  4. Click Resize All. The tool processes every image through the Canvas API right in your browser. You will see a progress counter and each image's status updating from Waiting to Processing to Done.
  5. Download your resized images. After processing, use the Download All button to save every image, or click the individual download button next to any specific image you need.

Tips for Getting the Best Results

  • If you need all images at the same size (for example, product photos at 800×800px), set the global dimensions once and let the tool apply them to every file in the batch.
  • Use the per-image override columns for images that need a different size from the rest of the batch. Only the images with custom values will use the override.
  • Choose WEBP as the output format when preparing images for a website. WEBP files are significantly smaller than JPG at similar quality, which improves your page load times.
  • For social media batches, resize to the platform's recommended dimensions: 1080×1080px for Instagram feed posts, 1280×720px for YouTube thumbnails, and 1200×630px for Facebook link previews.

What Is Bulk Image Resizing?

Bulk image resizing means changing the pixel dimensions of multiple images at the same time, instead of processing them one by one. For anyone who works with large numbers of photos regularly — product photographers, e-commerce sellers, social media managers, bloggers — doing images one at a time is painfully slow.

A bulk resizer lets you upload an entire folder of images, set a target width and height once, and resize everything in a single operation. This saves hours of repetitive work compared to using a desktop image editor for each file individually.

This tool runs entirely in your browser. It uses the HTML Canvas API to render each image at the new size, then exports the result in your chosen format. Since the processing happens locally, your images stay private and you do not need to wait for server uploads or downloads. Even on a mid-range laptop, a batch of 30 images typically finishes in under 10 seconds.

Frequently Asked Questions

How many images can I resize at once?
You can resize up to 50 images in a single batch using this bulk image resizer. Upload all your files at once by selecting them in the file picker or by dragging and dropping a group of images into the upload zone. You can also add more images after the initial upload.
Can I set different sizes for each image?
Yes. After uploading, each image appears in a table with its own override inputs for width and height. Enter custom dimensions for any image that needs to be different from the global setting. Images without overrides use the global width and height you set at the top.
What formats does the bulk resizer support?
The tool accepts JPG, PNG, and WEBP image uploads. When exporting, you can choose to keep each image in its original format or convert the entire batch to JPG, PNG, or WEBP. Converting to WEBP usually produces the smallest file sizes.
Are my images uploaded to a server?
No. All processing happens in your browser using the Canvas API. Your images never leave your device and are not stored anywhere online. This makes the bulk resizer completely safe and private for sensitive images like product photos or personal pictures.
Is there a file size limit per image?
Each image can be up to 50 MB in size. Most web images and phone photos fall well under this limit. If you have very large raw camera files, consider converting them to JPG first before using the bulk resizer, since raw formats are not supported by browser canvas rendering.
