Fast, private conversion
- Drag-and-drop or click to load common image formats.
- Lock aspect ratio, or use Scale (%) to resize both sides at once.
- Choose PNG, JPEG, or WEBP with quality control for compressed formats.
- Download directly—no uploads or external services.
Load and convert
Load & preview
Drop or select an image. Nothing leaves your device.
PNG, JPEG, WEBP and other browser-friendly formats are supported. No uploads.
Resize & format
Lock aspect ratio or scale both sides at once. Choose format and quality.
PNG keeps transparency, JPEG does not, and WEBP is often smaller. Metadata such as EXIF may be stripped during conversion.
Resize images without surprises
Use this tool when you need a quick resize or format conversion without uploading files. Decide the target size first, then choose the output format that matches how the image will be used.
Choose the resize method first
If you know the final width or height, enter that value and keep aspect ratio on. If you only need the image smaller or larger by a proportion, use Scale (%) instead of guessing both dimensions.
Pick the format for the destination
Use PNG for transparency and crisp UI graphics, JPEG for photos and broad compatibility, and WEBP when you want smaller modern web images. Quality affects JPEG and WEBP, but PNG ignores the quality slider.
Know what changes during conversion
Canvas-based conversion can strip metadata such as EXIF information. JPEG also removes transparency, so transparent areas will be flattened into an opaque background.
Check the result before replacing the original
Large images can fail because of browser memory limits. Keep the original file until you confirm the resized version has the dimensions, transparency, and file size you need.

Frequently asked questions
Are images uploaded anywhere?
No. Files stay in your browser and are processed with canvas. Nothing is sent to a server.
How do aspect ratio and scale work?
Keep aspect ratio recalculates the other side when you change width or height. Scale (%) multiplies the original size and fills both fields automatically.
How should I choose between PNG, JPEG, and WEBP?
Use PNG when you need transparency or crisp graphics, JPEG for photos and broad compatibility, and WEBP when you want smaller files with modern browser support.
What happens to transparent areas when I convert to JPEG?
JPEG does not support transparency. Transparent areas are flattened into an opaque background, so use PNG or WEBP if you need transparent output.
Will metadata or EXIF information be preserved?
Not always. Browser-based canvas conversion can strip metadata such as EXIF details, so confirm separately if you need to keep camera or location information.
