How to use Resize Image

  1. 01

    Upload your image

    Add the photo you want to resize, in any of the supported formats.

  2. 02

    Enter width and/or height in pixels

    Fill in a width, a height, or both — you never have to calculate the other dimension yourself.

  3. 03

    The server resizes with the ratio locked

    The image is scaled to fit inside your box with its aspect ratio preserved, so nothing stretches, and the source format is kept.

  4. 04

    Download the resized image

    Save the result at its new size — remember the tool only shrinks, so it never enlarges beyond your original dimensions.

Why choose our Resize Image

Never blurs from fake upscaling

The tool refuses to scale an image beyond its original dimensions, because upscaling cannot invent real detail — it only produces blur.

Aspect ratio always preserved

The image is always scaled proportionally to fit your box, so people, logos and text never come out stretched or squashed.

Resize in seconds

Resampling and re-encoding run on our servers and typically finish in a few seconds for photo-sized files.

Encrypted upload, automatic cleanup

Uploads travel over HTTPS, and both the original and resized image are deleted automatically within 24 hours.

Free to start

Anonymous visitors get 1 free server-side operation, and free accounts receive 3 conversions every 30 days.

Settings guide

Width and height (px)
Enter a width, a height, or both, in pixels. The image is scaled to fit inside that box with its aspect ratio preserved, so nothing gets stretched or distorted, and the output keeps the source format. The tool only shrinks images — it never enlarges them.

About the formats

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

PNG

PNG is a lossless raster image format created in the mid-1990s as a patent-free replacement for GIF. It is the standard choice for screenshots, logos, UI graphics, and any image that needs transparency.

PNG preserves every pixel exactly and supports a full 8-bit alpha channel, so text and sharp edges stay crisp. The downside is size: photographs saved as PNG are far larger than the same image as JPG or WebP. Support is universal in browsers and editors, making it a safe default for graphics — just avoid it for large photo collections.

WebP

WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.

Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.

Troubleshooting

The image did not get bigger
Enlargement is intentionally disabled: upscaling cannot invent real detail, it only produces blur, so the tool never scales an image beyond its original dimensions. If you asked for a larger size, the original is returned unchanged — start from a higher-resolution source instead.
The output is not exactly the width × height I entered
The aspect ratio is always preserved, so the image fits inside the box you gave and one dimension may come out smaller than requested. To get exact dimensions, first cut the photo to the desired ratio with the Crop Image tool, then resize it.
The resized photo looks slightly softer than the original
Downscaling resamples the pixels and re-encodes the file in its original format, so very large reductions can soften fine detail. Resize once, directly from the highest-resolution original, instead of shrinking in several passes.

FAQ

Will resizing keep the aspect ratio?
Yes. By default we scale your image to fit within the width or height you set without distorting it, so it never looks stretched.
Is the conversion private?
Yes. Your files are processed securely and deleted after conversion. We never share your photos.
Is there a file size limit?
Free accounts can upload files up to 50 MB. Paid users can upload up to 200 MB.
Can I enlarge a small image?
No. Enlargement is disabled on purpose — upscaling cannot invent real detail, it only produces blur, so the tool never scales an image beyond its original dimensions.
Will the output match the exact width and height I entered?
Not necessarily. The aspect ratio is always preserved, so the image fits inside the box you gave and one dimension may come out smaller than requested. For exact dimensions, crop first with the Crop Image tool.
Which formats are supported?
JPG, PNG and WebP. The output keeps the same format as your source image.
Does resizing count against the anonymous free limit?
Yes. Unlike crop or flip, resizing needs the full server pipeline, so it runs on our servers rather than in your browser — anonymous visitors get 1 free server operation before signing in.
