How to Resize Images

  1. Upload your images by dragging and dropping or clicking the upload area. You can select up to 10 images at once for batch processing.
  2. Choose resize mode: Use percentage to scale proportionally (e.g., 50% for half size) or specify exact pixel dimensions.
  3. Adjust quality and select output format if you want to convert the image type.
  4. Click "Resize" to process your images. For 3 or more images, you'll get an automatic ZIP download.
Pro tip: Use our Image Upscaler for AI-powered enlargement with better quality, or Compress JPG to reduce file size without changing dimensions.

About Image Resizing

Image resizing changes the pixel dimensions of your images. This is useful for preparing images for websites, social media, email attachments, or print. Our tool uses high-quality resampling algorithms to maintain image sharpness.

Resize Modes

  • By Percentage: Scale your image proportionally. 50% makes the image half its original size, 200% doubles it.
  • By Dimensions: Specify exact width and/or height in pixels. Enable aspect ratio lock to prevent distortion.

Supported Formats

This tool supports PNG, JPG/JPEG, WebP, AVIF, GIF, BMP, TIFF, HEIC/HEIF, and JPEG XL images. You can also convert between formats during resize by selecting a different output format. HEIC, TIFF, and JXL files are decoded server-side for broad browser compatibility, while most other formats are processed entirely in your browser for maximum privacy.

Frequently Asked Questions

Reducing size generally maintains quality well. Enlarging images can cause some blurring, but our tool uses high-quality resampling to minimize this. For best results when enlarging, consider using our Image Upscaler which uses AI to enhance quality.

Each image can be up to 20MB. You can upload up to 10 images at once for batch processing. For larger files, consider using our JPG Compressor or PNG Compressor first.

Most formats (PNG, JPG, WebP, GIF) are processed entirely in your browser - your images never leave your device. For formats like HEIC, TIFF, JXL, and BMP output, images are temporarily sent to our server for conversion and automatically deleted within 4 hours.

Yes! You can upload up to 10 images and resize them all with the same settings - or switch on Custom settings for this image to give any single image its own dimensions, quality or format while the rest keep the shared ones. When you process 3 or more images, you'll automatically get a ZIP file containing all resized images.

Yes. Click Crop above the preview, then drag a selection or pick a ratio preset (1:1, 4:3, 16:9, 9:16, or the original ratio) and apply it. The crop is non-destructive - "Reset crop" brings back the full image at any time, and in batch mode each image keeps its own crop. For rotation, straightening or exact pixel coordinates, use the full Image Cropper.

Common sizes include Instagram posts (1080x1080), Facebook cover (820x312), Twitter header (1500x500), and YouTube thumbnail (1280x720). For more specific sizes, try our Social Media Image Resizer which has all the presets built in.

EXIF data is metadata embedded in your images by cameras and phones - it can include GPS location, camera model, timestamps, and more. Stripping it (enabled by default) is recommended for privacy when sharing images online. Uncheck "Strip EXIF / metadata" if you need to preserve this data, for example when archiving photos or maintaining copyright information.

For screen and web use, 72 DPI is standard. For home printing, 150 DPI delivers good quality. Professional print projects - brochures, posters, and photo prints - typically require 300 DPI. Use 600 DPI only for ultra-high-quality fine art or detailed technical prints. Note that DPI does not change pixel dimensions - it tells printers how densely to place those pixels on paper.

The "By File Size" mode lets you set a maximum size (e.g. 500 KB or 2 MB) and the tool automatically adjusts quality and, if needed, dimensions to hit that target. It works best with JPG and WebP formats where quality directly impacts file size. This is ideal for email attachments, form uploads, passport photos, or any situation with file size limits. If you need a lossless format like PNG, consider using our PNG Compressor for better control.
