What is Resize Image and how does it work?

Resize Image is a free online tool from HuntPDF. Resize images to exact pixel dimensions. You upload a file, the work happens on our servers, and you download the result. There is nothing to install and no account to create.

How do I use Resize Image online?

Upload your file using the box above — drag it in, browse for it, or bring it in from your cloud storage. A preview appears so you can check you've picked the right file. Run Resize Image, then download the result. You can rename it before you save it.

Is my file secure when I use Resize Image?

Yes. The file you send to Resize Image travels over an encrypted HTTPS connection and is processed automatically on our servers. It is never made public, never shared with anyone, and nobody reads it.

Does HuntPDF store my files after Resize Image has run?

No. Your upload is deleted the moment Resize Image finishes with it, and the file it produces is removed as soon as you have downloaded it, or when you upload another file, or when you close the page. Nothing is kept, and nothing is used to train anything.

Will the original quality and formatting be maintained?

Yes. Resize Image is built to leave your content exactly as it is — only the change you asked for is applied. Nothing else about the file is altered or re-compressed.

Can I use Resize Image on mobile?

Yes. Resize Image works in any modern browser on phones and tablets — iPhone, iPad or Android — with nothing to install. You can upload straight from your device or from your cloud storage.

Can I rename my file before downloading it from Resize Image?

Yes. The file Resize Image gives you back keeps the name of the file you uploaded by default. If you'd rather call it something else, edit the name in the field next to the download button before you save it.

Do I need to install any software to use Resize Image?

No. There is nothing to download, install or sign up for — Resize Image is used from your browser and does the work on our servers, so it behaves the same on Windows, macOS, Linux, Android and iOS.

How long does Resize Image take?

Most files are finished in a few seconds. A large or page-heavy file takes a little longer, because Resize Image runs on our servers rather than on your device — but you won't be waiting around. You can upload files up to 250MB.

Is Resize Image free to use?

Yes. Resize Image is free, with no signup, no watermark on the result and no daily limit for normal use.

Can I resize several images at once?

Yes. Add a batch and every image is resized with the same settings. Handy for a set of product photos for an online shop.

Will Resize Image stretch or squash my photo?

Not unless you ask it to. The proportion lock is on by default, and the Stretch option only appears once you switch the lock off.

How do I resize an image for Instagram?

Choose Social media and pick Instagram post (1080×1080) or Story / Reel (1080×1920). Check the edges if your subject sits near the border.

Can I make an image bigger with Resize Image?

Yes, the percentage slider goes up to 200%. The image will have more pixels, but fine detail won't appear from nowhere, so a small, blurry photo stays soft.

Which formats does Resize Image accept?

JPG, PNG, WebP, HEIC, GIF, BMP, TIFF and AVIF, so iPhone photos work as they are.

Does resizing reduce the file size?

Usually, when you make the dimensions smaller, because there are fewer pixels to store. For a tight limit such as a 200 KB form upload, follow up with Compress Image, which lets you aim for a target size in kB.

Resize Image changes the pixel dimensions of a photo or graphic, by percentage, to an exact width and height, or to a ready-made social media size. It suits jobs like a 600×600 profile photo or a 6000-pixel camera shot that has to shrink for a website.

How to resize images online

Add one image or several by dropping them in, or pick them from your device, Google Drive, Dropbox or OneDrive (up to 260 MB each). Then choose how to resize. Percentage uses a slider from 5% to 200% and shows the new size in pixels as you move it. Exact size takes a width and height; leave the lock on and the other side follows, so nothing gets squashed. Social media applies a preset. Press Resize image, then download the result or open it in Crop Image with Continue with this file.

Resize Image options explained

With the lock off you get three fit choices. Fit inside keeps the whole picture within your box. Fill & crop fills the box exactly and trims whatever doesn't fit. Stretch forces the exact numbers even if that distorts the image. The social presets cover Instagram posts and Stories, a YouTube thumbnail (1280×720), a Facebook cover, a LinkedIn banner and a 600×600 profile photo. These fill the frame and centre the picture, so some edges may be trimmed.

Resize Image tips for a clean result

Scaling up past 100% gives you more pixels but can't add detail the camera never captured, so start from the largest original you have. If the goal is a smaller file rather than smaller dimensions, for example to get under an upload limit, resize first and then run Compress Image.
