    How to Use This Tool

    1. Upload one or more images.
    2. Choose "Percentage" to scale relative to each image’s own size, or "Exact dimensions" for a specific pixel size.
    3. In exact mode, pick a preset or type a width and height, and choose whether to maintain aspect ratio.
    4. Each image’s new dimensions appear automatically — download individually or all at once.

    How It Works

    Each image is drawn onto an off-screen canvas at the calculated target size and re-encoded in its original format. In percentage mode, both dimensions scale by the same factor. In exact mode with aspect ratio locked, the image is scaled to fit entirely within your target box without cropping or stretching.

    Example

    A 4000 × 3000 photo resized to fit within 1920 × 1080 with aspect ratio locked becomes 1440 × 1080 — scaled down evenly so nothing is stretched.

    Benefits

    • Resize an entire batch to consistent dimensions at once.
    • Presets for common sizes like HD and social media squares.
    • Aspect ratio protection prevents stretched, distorted photos.

    Important Notes

    Enlarging an image beyond its original size can make it appear soft or blurry, since no new detail is created. For best results, resize down from a larger original rather than scaling up a small image.


    Frequently Asked Questions

    What is the difference between the two resize modes?

    Percentage mode scales every image by the same percentage of its own original size. Exact dimensions mode fits every image within a specific width and height in pixels, either preserving its aspect ratio or stretching it to match exactly.

    Will resizing distort my images?

    Only if you turn off "Maintain aspect ratio" in exact dimensions mode. With it on (the default), each image is scaled proportionally to fit your target size without stretching.

    Can I resize images with different original sizes together?

    Yes. Each image is resized based on its own original dimensions and your chosen settings, so a batch of differently-sized photos all resize correctly at once.

    Can I make an image larger, not just smaller?

    Yes, entering a percentage above 100% or a target size larger than the original will scale the image up, though enlarging a photo significantly can make it look soft or blurry.

    Does resizing also compress the file size?

    Smaller dimensions usually produce a smaller file, but this tool focuses on dimensions only. Use the batch image compressor afterward for further size reduction.
