Image Resizer

Resize or circle-crop one JPG, PNG, or static WebP with precise dimensions, position, zoom, and layout controls. Processing stays in your browser.

JPG, PNG, or static WebP · up to 25 MiB and 40 megapixels · processed locally

Turn this on to crop the image to a real circular pixel mask.

How to resize an image

  1. Choose one supported image and confirm its dimensions.
  2. Select a size method, Fit, Crop, or Pad, an anchor, and output settings.
  3. Resize locally, inspect the result, and download the new file.

Fit without distortion

Fit preserves the source aspect ratio and places the full image inside the requested bounds. The output may be smaller on one axis.

Crop to exact dimensions

Crop fills the requested frame and removes overflow. Nine anchors control which part stays visible. Circle crop applies a true circular pixel mask; PNG and WebP keep transparent corners, while JPG uses your selected background.

Pad to an exact canvas

Pad preserves the full image and adds transparent or colored space to reach the exact requested dimensions.

JPG, PNG, and WebP output

Choose JPG for broad compatibility, PNG for lossless pixels and transparency, or WebP for a modern compact output. JPG requires a background for transparency.

Safety limits

PicRecast checks actual file signatures, rejects animated inputs, limits files to 25 MiB and images to 40 megapixels, and estimates memory before processing.

Local by design

The resize engine runs in your browser using a dedicated Worker when available, with a main-thread fallback. Image bytes are not sent to PicRecast servers.

Image resizer FAQ

Is my image uploaded?

No. This tool reads, resizes, encodes, previews, and downloads the image inside your browser.

Which input formats work?

JPG, PNG, and static WebP are supported. Animated PNG and WebP, GIF, HEIC, AVIF, and SVG are rejected.

What does quality change?

Quality affects JPG and WebP encoding. PNG output is lossless and does not expose a quality slider.

What is the difference between Fit, Crop, and Pad?

Fit keeps the whole image within bounds, Crop fills the frame and removes overflow, and Pad keeps the whole image on an exact-size canvas. Circle crop is a square Crop with a true circular mask.

Can resizing improve a small image?

Upscaling can increase pixel dimensions, but it cannot recreate detail that is absent from the source.

Is metadata preserved?

No. Browser re-encoding may remove EXIF and other metadata; JPEG orientation is normalized into output pixels.
