Resize Images by Dimensions or File Size

Resize up to 20 images at once. JPG, PNG, WebP, and Apple HEIC files supported. No ads.

    Type how big you want one side. The other side scales automatically to keep the shape — nothing gets cut or stretched. Shrink-only: we never enlarge.

    How it works

    1. Drop your images. Add up to 20 at once. JPG, PNG, WebP, and Apple HEIC files all work.
    2. Pick a mode. Resize to exact pixel dimensions, or shrink to a target file size like 500 KB.
    3. Click Resize. We process every image in the batch.
    4. Download your zip. Your files stay available for re-download for 24 hours.

    When to use this

    • Photos too big to email or upload. Modern phone cameras shoot 4-12 MB per photo. Most email and upload forms cap out well before that. Shrink first, send second.
    • Etsy, eBay, and Amazon listings. Each platform requires specific pixel dimensions and file-size limits. Get every listing photo to spec in one batch instead of one at a time.
    • Faster-loading websites. A 4 MB hero image slows your whole page down. Resizing to the actual dimensions your site uses (and shrinking the file size) makes pages snappier and helps SEO.
    • Profile pictures to exact dimensions. LinkedIn, Slack, X, and most platforms want a specific square pixel size. Drop your photo, type the size, done.
    • Need to hit a file-size limit instead? If your goal is a specific KB ceiling rather than exact dimensions, use the compress image to size tool.
    • Posting to social platforms? See resizing images for social media for the exact size each platform wants.
    • Wrong file format? If your images are in the wrong format — like iPhone HEIC files that won't open on Windows — use the convert image format tool to switch between JPG, PNG, and WebP.

    Common mistakes

    • Stretching to fit a shape. Forcing an image into new proportions distorts faces and objects. This tool always keeps the original aspect ratio — it scales proportionally, never squishes.
    • Trying to upscale. Making a small image bigger doesn't add detail — it makes it blurry. This tool (and every honest resize tool) only shrinks. If you need a larger image, you need a higher-resolution original.
    • Choosing PNG when JPG would be smaller. PNG is meant for graphics, logos, and screenshots with transparency. For photos, JPG is typically 5-10x smaller at the same visual quality.
    • Not checking the platform's required size. Etsy, Amazon, eBay, LinkedIn — they all have specific size requirements. Resize to their published spec, not a guess.
