About the Image Resizer and Compressor
Resizes one or more images to a maximum width and height, keeping their aspect ratio, with an optional format and quality change.
Online sellers use it to shrink product photos to fit a marketplace's size limits before listing, while web developers and bloggers use it to batch-resize images for a page without opening a design tool. It's one of many free image tools on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

FAQ
Frequently asked questions
Quick answers to common questions about the Image Resizer and Compressor.
What does the Image Resizer do?
It resizes one or more images to a maximum width and height you choose, keeping each image's aspect ratio, and can convert the output to JPEG, WebP or PNG at the same time.
Is the Image Resizer free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Is my image safe when I use this tool?
Yes. Every image is resized entirely on your own device using your browser's built-in Canvas API — nothing is uploaded to a server.
Does resizing crop my image?
No. The image is scaled down to fit inside the maximum width and height you set, keeping its full content and aspect ratio — it's never cropped or stretched.
Can I resize more than one image at once?
Yes. Add as many images as you like in one go; each is resized independently and listed with its own download link.
What does the quality setting control?
It controls the compression level for JPEG and WebP output — lower quality means a smaller file. It has no effect when you choose PNG, which is always lossless.
Can I use the Image Resizer on my phone?
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
Does the Image Resizer have any limitations?
It handles everyday photo sizes quickly. Extremely large images or a very long batch may take a few extra seconds to process, since everything runs on your own device.
