Are images uploaded to a server?

No. All processing is done locally in your browser using Canvas API. Your images are never sent to any external server.

How do I resize to a square for Instagram?

Please select 'Instagram Post (1080×1080px)' from the presets. Images with different aspect ratios will be automatically cropped or padded with margins.

Can I resize multiple images at once?

Yes. By selecting or dragging and dropping multiple files, you can batch resize them and save them all together in a ZIP file.

Will the image quality degrade after resizing?

There is almost no visible degradation when scaling down. When scaling up, pixel interpolation occurs, so fine details may become slightly blurrier than the original image.

What image formats are supported?

We support JPEG, PNG, WebP, and GIF (static). You can choose the output format among JPEG, PNG, and WebP, and adjust the quality (compression rate).

Is EXIF data (like location info) removed?

Yes. Since images are generated via the Canvas API, all EXIF parameters such as GPS info and shooting dates originally embedded in the photos are automatically stripped.

about,

Over

This is a free tool that converts the size (resolution) of an image to match the desired size. The biggest feature is that the "recommended sizes" for various social media and e-commerce sites such as Instagram, X, Amazon, and Rakuten are preset.

You can also choose the "fit method" when matching the size. If you do not want to crop the photo, you can select "Fit (add margins)", and if you want to display it to fill the screen, you can select "Cover (crop)".

No app installation is required. You can drag and drop multiple images (up to 20 images) at the same time to process them all at once and save them as a ZIP file. All processing is completed on your device using the browser's Canvas API, so there is no need to worry about your loaded photos being saved on an external server.

Glossary

Resize: The process of changing an image's pixel dimensions (resolution). Downsizing reduces file size while upsizing may introduce blurriness.
Aspect Ratio: The proportional relationship between an image's width and height. Common ratios include 16:9 (widescreen), 4:3, 1:1 (square), and 9:16 (stories).
Cropping: Removing unwanted portions of an image to keep only the desired area. Used for improving composition or fitting specific dimensions.
DPI / PPI: Dots/Pixels Per Inch — the density of dots or pixels in one inch. Print typically requires 300+ DPI while web images use 72 DPI.
EXIF Data: Metadata embedded in photos including date, camera model, GPS coordinates, etc. Resizing through Canvas API automatically strips this data for privacy.
Canvas API: An HTML5 API for manipulating image pixel data in the browser. This tool uses Canvas API for all resize and crop operations.
WebP Format: An image format by Google offering ~25-35% smaller file sizes than JPEG at equivalent quality. Ideal for faster web page loading.
