What Is a Bulk Image Resizer?
A bulk image resizer (also called a batch photo resizer or mass photo resizer) changes the size of many pictures in one pass instead of one at a time. You choose a single rule, such as 1080 px wide, a longest side of 1600 px, 50%, or an exact 2048 × 2048 square, and every photo in the batch follows it. It is how online stores prepare product photos, how bloggers keep pages fast, and how anyone shrinks a folder of phone pictures before emailing or uploading them.
This bulk photo resizer does it in your browser. Add up to 100 JPG, PNG, WebP, GIF, BMP, or HEIC images, preview the result, then resize in bulk and download a single ZIP. Photos are processed on your own device one after another, so nothing is uploaded, there is nothing to install, and it is free with no sign-up. It also works as a bulk image cropper and bulk crop tool: pick an exact size with Crop to fill to crop bulk images to the same shape.
How to Resize Photos in Bulk
Resize multiple images at once: batch resize photos in three steps, from a handful to a full folder.
Choose One Rule for All
Pick a preset or set Width, Height, Longest side, Percent, or Exact size. For an exact size, choose Fit with padding, Crop to fill (bulk crop), or Stretch. Then keep each file’s format or convert them all to JPG, PNG, or WebP.
Resize and Download the ZIP
Press Resize & Download ZIP. A progress bar shows each image as it is done, and the batch arrives as one ZIP, bulkresize-images.zip, with names like photo-resized.jpg. Single files can be downloaded from the list too.
A Batch Image Resizer Built for Big Folders
Resize 100 Images in One Go
Bulk resizing of photos used to mean desktop software. Here you mass resize images without repeating yourself: add up to 100 photos, set the size once, and the queue works through them on your device, one at a time so even phones keep up. Press again without changing anything and finished images are reused, not resized twice.
Width, Height, Longest Side or Percent
One multiple image resizer, five rules. Set a width and the height follows each photo’s shape, or the reverse. Longest side resizes portrait and landscape shots to the same maximum, 50% halves everything, and Exact size makes every image identical with padding or a crop. Turn on Don’t enlarge to leave small images as they are.
Convert Formats While You Resize
One image batch resize can mix formats. Keep original saves JPG as JPG, PNG as PNG, and WebP as WebP, and turns HEIC into JPG. Or convert the whole batch: JPG for small photo files, PNG for lossless graphics with transparency, WebP for the lightest web images. A quality slider sets the JPG and WebP compression.
Download Everything as a ZIP
With the image resizer bulk download, one click saves the whole batch as a ZIP with clear names (photo-resized.jpg, duplicates numbered), so nothing overwrites your originals. Need just one? Every row has its own download button. Camera data such as GPS location is not copied into the new files.
Bulk Crop Images to One Size
Batch crop images or pad them: real outputs of the exact-size presets, applied to the same mixed set of photos.
Square crop 1080 × 1080
Mass crop images for grids and profile feeds.
Portrait 1080 × 1350
Batch crop pictures to 4:5 for feed posts.
Thumbnails 400 × 400
Multiple crop for catalogs and galleries.
Pad 2048 × 2048 on white
No crop at all: the whole photo, same square.

Bulk Resize Tips
Get a consistent batch on the first try.
Mixed Orientations? Use Longest Side
Width mode makes portrait photos very tall. Longest side caps both shapes at the same size, so the batch looks even.
Don’t Enlarge Small Files
Tick Don’t enlarge so small images stay sharp instead of being stretched; for real enlargement use the Image Upscaler.
Match Format to Content
JPG for photos, PNG for logos and transparency, WebP for the smallest web files. Keep original is the safe default for any image resize bulk job.
Check One Before All
Click a few rows to preview the crop or padding on different shapes, then run the whole batch.

Bulk Image Resizer FAQ
Limits, formats, quality, and privacy.
Add all the photos above (drag a selection or click to pick several), choose one rule such as 1080 px wide or Longest side 1600 px, and press Resize & Download ZIP. Every image gets the same rule and the batch downloads as one ZIP. Use it as an image resizer in bulk for whole folders or for a single photo.
The image resizer batch limit is 100 images, each up to 40 MB. When a batch is done, clear the list and start the next one. Processing runs one image at a time on your device, so very large photos take a little longer on older phones.
Yes. It is a free bulk image resizer, and a free mass image resizer for big folders too, with no sign-up, no watermark, and no app to install. Because the work happens in your browser, it does not use credits.
No. Every photo is decoded, resized, and zipped inside your browser tab and never leaves your device. The resized files also leave out camera data such as GPS location.
Yes. Width, Height, Longest side, and Percent always keep each photo’s own aspect ratio. Exact size makes every image the same shape; choose Fit with padding to keep the whole photo, Crop to fill to bulk crop it, or lock the ratio to the selected image.
Yes. Batch resize image files and convert them in the same pass: keep original, or save the whole batch as JPG, PNG, or WebP. HEIC photos are saved as JPG when you keep the original format, since browsers cannot write HEIC.
Making photos smaller keeps them sharp; large reductions are done in smooth halving steps. Quality changes only if you enlarge (pixels are stretched) or pick a low JPG / WebP quality. The default 90% is hard to tell from the original.
Yes. This image bulk resizer works in Safari or Chrome on iPhone or Android: tap Add Images, select photos from your library (HEIC included), and the ZIP saves to Files or Downloads.
Press Resize & Download ZIP: when the progress bar finishes, one ZIP with every resized image downloads. A batch of one downloads as a single file, and each row also has its own download button.
For most pages, 1080 to 1920 px wide is plenty: 1080 for blog and social images, 1920 for full-width banners. Use Longest side 1600 for mixed orientations, save as JPG or WebP at around 80–90% quality, and compress further with Reduce Image Size if needed.

Run an image resizer batch free of charge: add up to 100 photos, pick one size, and download them all as a ZIP.
