Everything you need to know about resizing images online.
WebAuzar supports JPG, PNG and WebP formats. Files up to 50MB each are supported.
Select 'By Dimensions' mode, enter your target width and height in pixels. Enable the aspect ratio lock to avoid distortion — the tool will automatically calculate the correct proportions.
Select 'By Percentage' mode and drag the slider. For example, 50% makes the image half its original size. You can also scale up beyond 100% to enlarge images.
Yes! Upload as many images as you need. All images will be resized with the same settings. Download them individually or as a single ZIP archive.
When aspect ratio is locked, the tool maintains the original proportions of your image. For example, if you resize a 1920×1080 image to 1280 width, the height automatically adjusts to 720 — preventing stretching or squishing.
Quick Size presets let you instantly apply common dimensions: HD (1280×720), Full HD (1920×1080), Square (1080×1080), and Thumbnail (640×480). One click and the dimensions are set.
Downscaling (making smaller) usually preserves quality well. Upscaling (making larger) may reduce sharpness since no new pixel data exists. Use the quality slider to control output sharpness for JPEG and WebP.
Yes. Use the Output Format option to convert to JPEG, PNG, or WebP while resizing. For example, resize a PNG and save it as WebP for a much smaller file size.
Use our image resizer to reduce or enlarge image dimensions while preserving visual quality. Keep aspect ratio locked to prevent distortion.
Resize your image to smaller pixel dimensions or compress it. Smaller images load faster and improve website performance.
