Does resizing reduce file size too?

Yes, usually significantly — fewer pixels means less data to encode, on top of whatever compression the output format and quality setting apply.

What does "lock aspect ratio" do?

When enabled, changing the width automatically recalculates the height (and vice versa) to match the original image's proportions, so the result isn't stretched or squashed.

Can I resize multiple images to the same dimensions at once?

Yes — add multiple images, set your target size once, and click Resize; each image is processed with the same settings.

Image Resizer & Converter

100% client-side — your data is processed in this browser tab and never uploaded anywhere.

How to use this tool

Drop in one or more images.
Set a target width (and height, if aspect ratio isn't locked) — or use the 25/50/75/100% quick-scale buttons.
Pick an output format and quality, then click Resize.
Download each resized image individually.

Common mistakes to avoid

Don't unlock aspect ratio unless you actually want the image stretched — it's the most common way people accidentally distort a photo.
Upscaling (setting dimensions larger than the original) will make the file bigger without adding real detail — this tool won't stop you, but it won't look sharper either.

How GetByteRush compares

Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:

Feature	GetByteRush	Typical online tools
Image ever leaves your device	No — 100% client-side	Yes, on upload-based resizers
Batch resizing	Yes, unlimited	Often limited or paywalled
Format conversion included	Yes (JPEG/WebP/PNG)	Sometimes a separate tool
