Why Use This Bulk Image Resizer?
Resize Multiple Images at Once
Add a group of photos, graphics, or product images and process the complete batch in one run instead of resizing files one by one.
Set Exact Image Dimensions
Enter a custom width and height for every image. Keep the aspect ratio locked for proportional scaling or unlock it when a fixed canvas size is required.
Keep JPG, PNG, and WebP Formats
Each resized file keeps its original image format, so JPEG photos stay JPEG, transparent PNG files stay PNG, and WebP assets stay WebP.
How to Bulk Resize Images Online
Upload Multiple Images
Drag and drop several JPG, PNG, or WebP files into the bulk image resizer. A preview and original pixel dimensions appear for every file.
Choose Width and Height
Set the target dimensions for each image. Leave the aspect ratio locked to scale proportionally, or unlock it to control width and height independently.
Resize and Download a ZIP
Select Resize All Images to process the batch. Download individual files or save every successful result together in one ZIP archive.
Bulk Resize Images for Every Workflow
Batch Resize Product Images
Prepare product photos for store listings, category pages, marketplace uploads, and catalog thumbnails with consistent target dimensions.
Resize Photos for Websites
Scale large photos before adding them to landing pages, blog posts, galleries, or portfolios so their pixel dimensions match the layout.
Prepare Social Media Images
Create resized copies for posts, profile graphics, campaign assets, and content calendars without repeating the same export workflow for every file.
Preserve Image Proportions
Use the aspect ratio lock to prevent accidental stretching while changing width or height across a collection of differently sized images.
Process Images Privately
The batch image resizer runs locally in your browser. Your source images are processed on your device rather than uploaded to an image-processing server.
Download Resized Images Together
Finished files receive dimensions in their names and remain available on the results page for individual downloads or a single ZIP download.
Bulk Image Resizer FAQ
What is a bulk image resizer?
A bulk image resizer is a tool that changes the pixel dimensions of multiple images in one processing session. Add several files, choose the width and height for each image, run the batch, and download the resized results together.
How do I bulk resize images online?
Upload multiple JPG, PNG, or WebP images, enter the target dimensions, and select Resize All Images. The tool processes every valid file in your browser and opens a results page where you can download individual images or one ZIP.
Can I resize multiple images to exact dimensions?
Yes. You can enter an exact width and height for each image in the batch. Keep the aspect ratio locked when you want proportional resizing, or unlock it when the output must use independently specified dimensions.
Which formats can I resize in bulk?
You can bulk resize JPG and JPEG photos, PNG images, and WebP files. Each successful result keeps the corresponding source format, including PNG transparency where the browser supports it.
Does the bulk image resizer upload my files?
No. Image decoding, canvas resizing, and result generation happen locally in your browser. The source files do not need to be sent to our servers for processing.
How does the aspect ratio lock work?
The aspect ratio lock recalculates height when you change width, or width when you change height. This keeps the original proportions and prevents stretched or squashed results. Unlock it only when you intentionally need separate width and height values.
Can I download all resized images in one ZIP?
Yes. After at least one image is resized successfully, the results page lets you download all completed files in one ZIP archive. Duplicate filenames receive a sequence number so no image is overwritten.
Will bulk resizing reduce image quality?
Downscaling generally keeps images sharp because the resizer uses high-quality browser smoothing. Enlarging an image cannot create missing detail, so avoid extreme upscaling when clarity matters. JPEG files are exported at a high quality setting, while PNG and WebP retain their matching formats.
Is this bulk image resizer free?
Yes. You can resize multiple images online without creating an account, installing software, or adding a watermark to the output files.
