Image Resizer

Add images — drag in JPG, PNG, or WebP files, or click to browse. You can add several at once.

Set dimensions — choose a preset (Instagram, Full HD, 4K, YouTube Thumbnail) or enter a custom width and height in pixels or percent. Keep "Lock Aspect Ratio" on to avoid stretching.

Choose output — pick JPG, PNG, or WebP and a quality level, set the interpolation, and tick "Remove Metadata (EXIF)" to strip camera and location data.

Apply and download — click "Apply Settings to All", then download each image or "Download All (ZIP)". ```

Enter the width and height you need in the dimension boxes with the unit set to "px", then apply the settings. If you only know one side — say a 1200px width — type it with "Lock Aspect Ratio" on and the height fills in automatically to keep the proportions. To scale relative to the original instead, switch the unit to "%" and enter a percentage.

Scaling an image down keeps it looking sharp, especially with the High Quality (Lanczos/Bicubic) interpolation setting. Quality only suffers noticeably when you enlarge a small image well beyond its original size, since there's no extra detail to add. For the cleanest results, resize down rather than up, and keep the output quality at 90 or above for photos.

Keep "Lock Aspect Ratio" turned on — the lock button next to the width and height. With it on, changing one dimension updates the other automatically so the proportions stay correct. Turn it off only when you deliberately want to stretch an image to a fixed size; otherwise leaving it on prevents the squashed or stretched look.

Usually, yes. Fewer pixels means less data, so a resized image is typically smaller on disk than the original. If you need to hit a specific file size, resize first to the dimensions you actually need, then run the image through the Image Compressor and adjust the quality. Resizing changes pixels; compressing squeezes the file further.

Yes. The preset menu includes the common sizes: Instagram Post (1080×1080), Instagram Story (1080×1920), Full HD (1920×1080), 4K (3840×2160), and YouTube Thumbnail (1280×720). Pick the one you need and the width and height fill in for you. Choose "Custom Dimensions" if you want to enter your own exact size instead.

Yes. Drag in a batch of images, set your dimensions, format, and quality once, then click "Apply Settings to All" to process every image with the same settings. When they're done, use "Download All (ZIP)" to save the whole set in one folder. It's the fastest way to standardise a folder of photos to one size.

Yes. Pick JPG, PNG, or WebP as the output format, and set a quality value for the result. This lets you resize and convert in one step — for example, take a large PNG and output a smaller WebP for the web. Choose PNG if you need to keep a transparent background, since JPG doesn't support transparency.

It can, and "Remove Metadata (EXIF)" is ticked by default. EXIF data can include the camera model, settings, and even GPS location where a photo was taken. Stripping it on resize keeps that information out of images you share online. Untick the box if you specifically need to keep the metadata, such as for cataloguing your own photos.

No. The resizer runs entirely in your browser, so your images are processed on your own device and never uploaded. Nothing is stored after you close the tab. This makes it private for personal photos and fast even on a slow connection, because there's no waiting for files to travel to and from a server.

It controls how pixels are calculated when the image is scaled. "High Quality (Lanczos/Bicubic)" produces smooth, natural results and is the right choice for photos and most graphics. "Pixelated (Nearest Neighbor)" keeps hard edges without blending, which is what you want for pixel art or when you intentionally want a blocky, retro look.

You can, but with limits. Enlarging adds no real detail — it only stretches the pixels you already have — so a small image scaled up will look softer, and a lot of upscaling can look blurry. The High Quality interpolation softens this, but for the sharpest results it's always better to start from the largest original you have.

Yes. It runs in your phone's browser with nothing to install, so you can resize photos on Android or iOS before posting or emailing them. Single images and small batches resize smoothly on a phone; very large 4K batches use more memory and are more comfortable on a laptop, but everyday resizing works fine on mobile.
