Guide • Updated: 2026-11-11 • Free, in your browser — your photos are never uploaded
Resizing photos one by one is slow. If you have a whole folder to prepare — a job application with certificates, a college form with documents, or product photos for an online shop — doing them one at a time can take an hour.
Batch resizing does them all at once. You select your photos, pick one size, and download everything together as a single ZIP file. This guide shows you how.
Put all the photos you want to resize into a single folder on your phone or computer, and check that they are all the right photos — batch tools process everything you select, so a wrong file in the folder means a wrong file in the output. If your photos are different sizes or orientations, that is fine; the tool handles each one on its own.
Open ResizeHub’s Batch Image Resizer and select your photos — you can pick up to 50 in one go. You will see a list of the files you added, with their original sizes. If you added one by mistake, remove it from the list before you start.
Choose the size you need — for example, a maximum width, a fixed dimension, or a KB target. Every photo in the batch gets the same treatment, so pick the size your form or shop actually asks for. If your photos have different aspect ratios, the tool keeps each photo’s own ratio so nothing gets stretched or squashed.
Press the process button and wait for all the photos to finish — you will see a progress list as each one completes. When everything is done, press Download All as ZIP. You get a single ZIP file containing all your resized photos, with their original names kept so you can tell them apart.
Open the ZIP on your device and check two or three photos: the size should be right, the faces and text should be sharp, and the file names should match your originals. If one photo looks wrong, re-run just that photo on its own instead of redoing the whole batch.
Batch resizing turns an hour of clicking into a few minutes: one folder, one size, one ZIP. And because everything runs in your browser, your photos are never uploaded to any server.
