Resize images to exact pixel dimensions or by percentage — batch, aspect ratio locked, nothing uploaded.

This is a free online image resizer that changes the pixel dimensions of your photos entirely inside the browser. Give it an exact size — 1920×1080 for a wallpaper, 1080×1080 for a square avatar, 800×600 for a document — or scale everything by a percentage such as 50% or 25%. Keep the aspect ratio locked and the tool works out the missing side for you, so nothing ends up stretched; unlock it when a layout demands exact numbers. Drop in a whole folder of images and they are all resized with the same settings, then downloaded one by one or as a single ZIP. Your files are never uploaded: the resizing happens on your own device, which makes it fast, private, watermark-free and completely free. Enlarging is allowed too, though no tool can invent detail that was never captured — an upscaled image will always look softer than the original.
Drag images into the upload area or click to pick them. Add as many as you like — PNG, JPEG, WebP, AVIF, GIF, BMP and HEIC/HEIF all work.
Choose pixel size or percentage, type a width and/or height, or tap a preset such as 1920×1080 or 50%. Keep “Lock aspect ratio” on to avoid distortion.
Click “Resize images” to redraw everything locally. Compare the original and new dimensions in the table, then download each file or grab them all as a ZIP.
Type the width and height you need and get precisely that — ideal for upload boxes, banner slots and print layouts with a hard size requirement.
Scale by 50%, 25% or any value up to 400% when you have no fixed target and simply want the image proportionally smaller or larger.
With the ratio locked, filling in one side derives the other, and filling in both fits the image inside that box — so photos never come out squashed or stretched.
1920×1080, 1280×720, 1080×1080, 800×600, 50% and 25% cover the sizes people ask for most, from Full HD wallpapers to square social avatars.
Load dozens of images, apply one setting to all of them and download the whole set as a ZIP instead of repeating the same job image by image.
Decoding, resampling and re-encoding all happen in your browser. Nothing is sent to a server, and there is no watermark, no sign-up and no file-count limit.
Many platforms want a square avatar — resize to 1080×1080 or 800×800 and your photo fits the frame without an awkward automatic crop.
Forms, job boards and government portals often cap image dimensions. Shrink the long side to the allowed number and the upload goes through first time.
Serving a 6000px photo in an 800px slot wastes bandwidth. Resize it to the size it is actually displayed at and pages load noticeably quicker.
Scale screenshots and photos down before dropping them into Word, Google Docs or a presentation to keep the file manageable and the layout tidy.
No. The resizing runs entirely in your browser using the canvas API — your files are read from disk, redrawn locally and handed straight back to you. Nothing is sent to a server, so even confidential images stay private and the tool keeps working on an unstable connection.
Keep “Lock aspect ratio” switched on. Fill in only the width (or only the height) and the other side is calculated from the original proportions. If you fill in both, the image is scaled to fit inside that box, so it is never stretched — one side may simply come out smaller than the number you typed.
Yes — enter a larger size or a percentage above 100% and the image is upscaled. Be realistic about the result: enlarging can only interpolate pixels that were never captured, so the output looks softer than the original. That is fine for a moderate increase, not for rescuing a tiny thumbnail.
Yes. Drop in a whole batch and every image is resized with the same setting. In percentage mode each one is scaled relative to its own size; in pixel mode with the ratio locked each one is fitted into the box you defined. Download them individually or as a single ZIP.
No. Each image is re-encoded in its original format — a PNG stays a PNG, a JPG stays a JPG. If you also need a different format, use our image converter; if you need a specific file size in KB, use the image compressor.
PNG, JPEG, WebP, AVIF, GIF and BMP, plus Apple's HEIC/HEIF from iPhone photos. PNG, JPEG, WebP and AVIF keep their original format on output; HEIC, GIF and BMP are decoded in the browser and saved as JPG, because browsers cannot write those formats back out (an animated GIF also keeps only its first frame).
Usually yes — fewer pixels means fewer bytes, and the table shows the before/after size for every image. This tool optimises for dimensions rather than for bytes, so if you must hit an exact limit such as 200KB, use the image compressor instead.
