How it works

From source files to finished batch

01

Choose your source images

Select images to open resize image by percentage in the studio. The matching workflow and preset are selected automatically; you can still change them before export.

02

Review the preset

A 50% scale halves both width and height, reducing total pixel count to roughly a quarter. Mixed-resolution photos keep their individual proportions and scale consistently.

03

Process and save copies

Preview the selected image, then process the whole batch. Compare the real dimensions and encoded size before saving individual results or one ZIP. Your originals are not overwritten.

Common uses

Built for everyday image work

A focused resize workflow

Scale every image relative to its own original dimensions. Use a 50% preset or choose another percentage without calculating pixel sizes.

One image or a whole folder

Use the same settings across up to 50 files. Check unusual compositions or mixed-resolution images before processing the batch.

Combine with other edits

Add resize, crop, rotate, color, watermark, or compression steps in the studio. The workflow runs in the displayed order and shares one final output format.

Worth knowing

Keep the output predictable

Choosing the right settings

A 50% scale halves both width and height, reducing total pixel count to roughly a quarter. Mixed-resolution photos keep their individual proportions and scale consistently.

Format and quality limits

The supported range is 1–200%. A 200% enlargement is ordinary resampling, not AI upscaling; browser canvas limits still apply.

Local processing and source limits

Files stay in browser memory. Each source can be up to 40 MB, within the 16,384-pixel edge and 80-megapixel canvas limits. HEIC uses the first contained image; AVIF requires browser decoding. Export is JPEG, PNG, or WebP, not HEIC or AVIF.

FAQ

Resize Image by Percentage questions

How do I use resize image by percentage?

A 50% scale halves both width and height, reducing total pixel count to roughly a quarter. Mixed-resolution photos keep their individual proportions and scale consistently. Choose images above to load these settings automatically, or open the empty studio to adjust them first.

What should I check before downloading resize image by percentage results?

The supported range is 1–200%. A 200% enlargement is ordinary resampling, not AI upscaling; browser canvas limits still apply.

Does choosing images upload them?

No. The editor decodes and processes image files on your device. It loads its code from this website, but does not send your image contents to an image-processing service.
