Resize Images to Exact Pixels
Set the width and height in pixels or pick one of 4 ready sizes, then choose a mode: cover, contain or fill.
Your photo is sent to the Pixelift server in Germany and scaled with the Sharp library. It is not passed to any AI provider. Without an account we don't save the result; when you're signed in, the original and the result are saved in your account history.

What is Resize Image?
Resize Image is a free tool in Pixelift that works online with no installation. Set the width and height in pixels or pick one of 4 ready sizes, then choose a mode: cover, contain or fill. Up to 8192 px per side. Free, no account; without signing in there is a daily limit of tries. Engine: Sharp. No credits are charged per result. Files go to our server in the EU; if the tool uses an AI model, it runs at a provider from our subprocessor list. We never train models on them.

Resizing on the Pixelift server
Your photo goes to the Pixelift server, where the Sharp library scales it. The result keeps the input format (JPG, PNG or WebP), and each side can be up to 8192 px.
- Cover: fills the whole frame, edges may be cropped
- Contain: the whole photo without cropping, empty space is black
- Fill: exact dimensions at the cost of proportions
- No AI models and no credits
What to expect — Works best when
- You're shrinking a photo to specific dimensions
- A platform requires an exact pixel size
- You have one photo to resize
What it won't do
- It adds no detail when enlarging (use the AI Upscaler for that)
- It has no aspect-ratio lock: you type the dimensions or pick a mode
- It doesn't resize several photos at once
- It doesn't set DPI for print
Tips
- Contain keeps the whole photo; cover fills the whole frame.
- Use fill only when the input and output proportions are almost the same.
- Shrink from the highest-quality original.
- To enlarge with detail, use the AI Upscaler.
What this tool is (and is not) for

- •Specific pixel dimensions
- •Social media standards (Instagram, Facebook, banner)

DO NOT use for — try instead
- •Enlarge with quality preservation (AI)Try instead: Upscaler— AI upscaling preserves detail
- •Shrink file size without changing dimensionsTry instead: Image Compressor— compression keeps dimensions
- •Cut a portion / change aspect ratioTry instead: Crop Image— cropping, not scaling
- •Add background / extend the frameTry instead: Image Expand— AI draws an extension
Frequently Asked Questions
Is resizing free?
Yes. It uses no credits and works without an account. Without signing in there is a daily limit of tries per IP address, and for everyone a limit on the number of operations in a short time.
What is the difference between cover, contain and fill?
Cover fills the whole frame and may crop the edges. Contain fits the whole photo without cropping and fills the empty space with black. Fill gives the exact dimensions but distorts the proportions.
Can I enlarge a photo?
Yes, up to 8192 px per side, but plain scaling adds no detail and an enlarged image will look soft. To enlarge with added detail, use the AI Upscaler (it costs credits).
Are my images uploaded anywhere?
Yes, to the Pixelift server in Germany, where the Sharp library scales them. They are not passed to any AI provider. Without an account we don't save the result; when you're signed in, the original and the result are saved in your account history.
Which formats are supported?
JPG, PNG and WebP up to 20 MB. The result keeps the format of the input file.
Can I resize several photos at once?
No, the tool resizes one photo at a time.
