Why use this tool

  • No file size limit

    Full-size photos and long documents, straight from your device.

  • Nothing is uploaded

    Processed entirely in your browser. Your files never leave your device.

  • No signup needed

    Open the tool and go. No account, no email.

Choose website image dimensions from the space in your layout. This tool starts with a 1920 × 1080 banner, with 800 × 600 blog and 1280 × 720 landscape alternatives. These are editable examples, not universal website requirements. A narrow article column rarely needs the same source size as a full-width banner.

Resize and download in three steps

  1. Add your images

    Choose one or more supported photos, or drop files onto the page.

  2. Check dimensions and framing

    Use the preset, compare the preview and choose fit, format and quality.

  3. Resize and save

    Process the selected files, check their actual output dimensions and download them individually or in a ZIP.

Pixel dimensions and page speed are different tasks

Resizing reduces the number of pixels; encoding determines the file's byte weight. After export, use image compression if your site has a file-size budget. Configure responsive image variants, width/height attributes and meaningful alt text in your website code. This tool produces the image file; it does not edit HTML or guarantee a PageSpeed score.

Choose the crop before resizing

Crop to fill creates the requested outer frame with a centered crop. Fit inside keeps the whole image and adds padding; Stretch changes proportions. Check the preview and compare Original before processing. The aspect-ratio lock preserves each source's proportions when you edit one dimension. Leave it off when both output dimensions must stay exact. Use Crop Image to position a subject manually.

Formats, quality and batch downloads

Open JPG/JPEG, PNG, WebP or HEIC/HEIF files. Choose JPG, PNG or WebP for output, or keep the source format where supported; HEIC defaults to JPG. JPG and WebP offer a quality slider, while PNG is lossless. Transparent padding is white in JPG. Settings apply to all files, but selection controls which files are processed. Download individual results or a ZIP. Files are processed in your browser without an account.

Starting sizes and output settings

Presets are editable. Keep both values unchanged for the exact canvas shown.

A practical resizing workflow

  • Check the framing

    Compare the original and preview. Choose cropping or padding before processing the selected files.

  • Download a batch

    Use the same settings across your selection and save finished files individually or together in a ZIP.

Frequently asked questions

Which website image size should I use?
Match the intended layout and device display density. The banner and blog presets are starting points; change both dimensions for your actual content slot.
Can I resize without cropping?
Yes. Choose Fit inside to keep the whole photo. It adds padding when the source and target aspect ratios differ.
Will resizing meet a limit in KB?
Not necessarily. Pixels describe dimensions, while KB measures file size. Use the compressor afterward and recheck dimensions if it scales the image down.
Can I process several photos together?
Yes. Add multiple files, select the ones you need and process them together. Each row has its own status and download, with ZIP available for the completed selection.
Does enlarging an image restore detail?
No. Resizing can create a larger file in pixels but cannot reconstruct detail missing from the original.
