What this free image resizer does

This tool is a photo and picture resizer: it changes the pixel width and height of an image you upload. That controls how large the picture appears at normal display scale. It is different from compression, which mainly targets file size in bytes. Stretching both dimensions without preserving aspect ratio can make subjects look warped.

Use it when a website template, social slot, form, or document asks for exact dimensions. After you resize an image, you can compress the image if the file is still too large to upload.

Photo resizer vs picture resizer — same tool, different jobs

Whether you call it a photo resizer or a picture resizer, the job is the same: set exact pixels so the file fits the place you will use it. Photos from a phone are often thousands of pixels wide; forms and profile slots usually need a few hundred. Downscaling first makes uploads faster and keeps layouts from breaking.

Reduce image size (dimensions)

Enter a smaller width or height to reduce image size on screen. With aspect ratio on, one dimension is enough — the other scales automatically so the photo does not stretch. If you meant fewer kilobytes rather than fewer pixels, finish with the image compressor.

Increase photo resolution online for free

Enable “Allow upscaling,” then enter larger width and height values. That increases the pixel count so a small picture can fill a bigger canvas. Upscaling cannot invent real camera detail — results often look soft if you scale far beyond the original. Use it for modest enlargements, not for recovering lost sharpness.

Crop, then resize

Optional crop lets you keep a face, product, or subject before the dimensions change. Combine crop with Cover fit when a slot needs an exact box and you care which part of the picture fills it.

Why people resize images online

• Fixed slots. Templates, CMSs, and social platforms reject or crop files that do not match their pixel box.
• Faster pages. Serving a 6000-pixel photo in a 800-pixel column wastes bandwidth. Reducing dimensions first cuts weight before compression.
• Forms and applications. Job portals and school systems often require an exact width and height.
• Print and slides. Matching the canvas of a document or deck avoids stretch when the picture is dropped in.

Formats, limits, and privacy

Accepted uploads: JPEG, PNG, WEBP, GIF, BMP, TIFF, AVIF, HEIC. Max 200 MB per image.

Limitations: Upscaling cannot invent real detail. Cover fit may crop edges. Savings in file size from resizing alone depend on the original; compress afterwards if you still need fewer kilobytes.
