Bulk Image Resizer for Consistent PNG Canvases

Resize multiple images on your device without uploads or AI credits. Preserve proportions, choose canvas margins, and download transparent or solid-color PNGs.

Drop up to 20 images here, or choose files

JPG, PNG or WebP · up to 5 MB and 16 MP per image

Resizing runs on your device. No AI credits are used.

Change delivery size without changing the subject

Use this tool when the source already has the background you want, or when a finished cutout needs another frame. Resizing does not remove a backdrop, identify a foreground subject, or repair a blurred photo.

Select up to 20 JPG, PNG, or WebP files, each up to 5 MB, 16 megapixels, and 4096 pixels per side. This local workflow can accept smaller images than the AI tool’s 256-pixel minimum. A larger frame does not recreate missing source detail.

Understand contain fitting and empty space

Contain fitting scales proportionally so the complete source fits inside the canvas. When a portrait photo enters a landscape frame, extra room may appear at the sides. That space is expected; stretching would change the subject’s shape.

A margin reserves room between the fitted image and canvas edge. Check the smallest output dimension before choosing a large margin. If the settings leave no useful drawing area, reduce the margin or choose another canvas size.

Decide which background belongs in the file

Transparent PNG preserves empty areas around a transparent source. A solid export color fills the available background. If the original still has an opaque backdrop, resizing keeps those original pixels; selecting transparency does not remove them.

Use the product background remover first when the subject needs separating, then return here for size-only delivery. The export is PNG whether you choose transparency, white, or another solid color.

Keep local work and downloads manageable

The current browser processes the files on this device. No AI quote or credits are needed, but browser memory and the number of large images can affect the wait. Keep the page open until you have saved your files.

Preview the dimensions before downloading selected images or a ZIP. If the browser cannot prepare an archive, or the size-limit message asks for a smaller set, reduce the selection and download in parts. Keep the originals for another delivery size.

How to use the bulk image resizer

Select the image set
Add originals or finished cutouts. Choose complete, recognizable files rather than repeated copies.
Set canvas and margin
Choose the dimensions needed by the destination and leave space around each source.
Review proportions and background
Check each fit. An opaque source backdrop remains part of the image even when you select a transparent canvas.
Download locally prepared PNGs
Save selected images or the set. Keep the page open until downloads finish and split oversized selections when needed.

Frequently asked questions

Does the bulk image resizer upload images or spend credits?

No. This size-only workflow runs on your device and does not call AI removal. It needs no paid quote. Cloud background removal is a separate tool with its own allowance or credit price.

Can resizing remove the original background?

No. An opaque original background remains part of the image. Remove it with the product background remover first if you need an isolated subject, then resize the finished PNG.

Will all products have the same apparent size?

A shared canvas aligns file dimensions. Source proportions and margins determine how large the subject appears. Inspect the set visually; a tall and a compact product can look different on identical canvases.

Can I enlarge a small photo into a detailed large image?

The resizer can scale or place the source but cannot recover absent detail. Check the intended viewing size and use a sharper original when an enlarged image looks soft.
