How to use

  1. Drop an image or click browse to choose one.
  2. Pick a photo preset (passport, resume, LinkedIn) or set a custom width, height, or scale.
  3. Optionally change the output format (PNG, JPG, WebP) and quality.
  4. Click Resize, then Download.

What does it do?

The tool decodes your image into a browser canvas, then re-draws it at the target dimensions using high-quality bilinear interpolation. You can keep the original format or convert between PNG, JPG, and WebP. Photo presets (US / EU / UK / KR / JP / CN / CA passport, Korean and Japanese resume photos, LinkedIn square) use the standard 300 DPI pixel equivalents and center-crop the source so the subject is not stretched.

Example

Input:  3024 × 4032 HEIC photo from an iPhone, 3.1 MB
Target: Korean resume photo (3×4 cm @ 300 DPI = 354 × 472)
Output: 354 × 472 JPG, quality 90, center-cropped → ~48 KB

Why is my resized image blurry?

Most image-resize complaints come from one of these six issues.

  • Upscaling past the source resolution. Going from 400×400 to 1200×1200 cannot add sharpness — the browser just interpolates between pixels. Always resize down from the highest-resolution original.
  • Wrong aspect ratio → stretched image. If you uncheck "Lock aspect ratio" and type mismatched width / height, the picture is squashed. Re-lock the ratio or pick a preset that center-crops instead.
  • Quality too low for JPG. Below 60 JPG starts to show blocking artifacts and color banding, especially in skies. Use 80–92 for web, 92+ to keep it near-original.
  • Converting a screenshot or logo to JPG. JPG is built for photos. Screenshots, text, and flat-color graphics develop halos and color fringing. Keep them as PNG.
  • Canvas max-dimension error. The tool caps each side at 16384 px. Beyond that, most browsers refuse to allocate the canvas and the resize fails silently or throws.
  • EXIF rotation lost. If your result is rotated the wrong way, your source had an EXIF orientation flag. The tool respects it (imageOrientation: 'from-image'), but some old browsers do not — update your browser if that happens.

Is my data private?

Yes. We don't save the image you drop here, and we don't keep the resized version you download. Nothing is stored, logged, or retained — everything is discarded as soon as you close or refresh the tab. There's no record on our side of what you resized. Feel free to verify in your browser's developer tools.

Frequently asked questions

Why does my resized image look blurry or soft?

Blurriness usually comes from scaling a small image up past its native resolution — a 400×400 source cannot be made sharper by resizing to 1200×1200. The browser interpolates pixels that do not exist. Start from the highest-resolution original you have, and only scale down.

Why did my PNG get larger after resizing?

If you resized up, the file has more pixels to store. If you converted from JPG to PNG, PNG is lossless and stores every pixel exactly, which is bigger than JPG for photos. For photos, keep the output as JPG or WebP. Use PNG for screenshots, logos, and graphics with flat colors.

What quality setting should I use for JPG or WebP?

Quality 85–92 is near-indistinguishable from the original for most photos and saves considerable space. Quality 70–80 is a good web default. Below 60 you will start to see blocking and color banding, especially in skies and gradients.

Is there a maximum image size this tool can handle?

The tool caps each output dimension at 16,384 pixels, which is the Canvas API safe limit in most browsers. Very large source files (over ~100 MP) may also fail to decode on low-memory devices. If you hit that, downscale in two passes or use a smaller source.

Does the tool strip EXIF metadata when it resizes?

Yes. Because the image is re-encoded from a canvas, EXIF, GPS, and other metadata do not carry over to the output. If you need to keep metadata, use a different tool. If you specifically want to remove it without touching pixels, use the EXIF Metadata Remover.

Do you save the images I resize here?

No. We don't save the image you drop in, and we don't keep the resized copy you download either. Nothing is stored or logged on our side, and everything is discarded the moment you close or refresh the tab. You can verify in your browser's developer tools if you'd like.
