Resize multiple JPG, PNG, GIF or SVG images by pixels or percentage. Everything stays in your browser.
JPG, PNG, GIF or SVG · up to 20 files · 20 MB each

All image processing happens locally in this browser. Files are not uploaded, stored or sent to FreeToolsWeb.
Set an exact width or height, fit mixed images inside a pixel box, or scale a whole batch by percentage. Preview the new dimensions and download each result or one ZIP without creating an account.
Process up to 20 JPG, PNG, GIF or SVG files, 20 MB each and 100 MB per batch. Output dimensions are limited to 12,000 pixels per side and 40 megapixels.
Files stay in browser memory and disappear when you clear the list or close the page. Analytics events contain only aggregate actions such as file count and completion; they never contain image data or filenames.
Resize photos before adding them to websites, stores, email, documents or forms that require maximum dimensions. A correctly sized image avoids transferring pixels that a screen will never display and makes mixed batches more consistent.
Pixels are best when a destination specifies a width or height. Percentage applies the same relative scale to every file. Keep aspect ratio enabled to avoid distortion; when both pixel values are filled, they act as a maximum box.
JPG and PNG stay in their original formats. Animated GIF frames are resized and re-encoded with their timing, while SVG keeps its vector shapes and receives new display dimensions. Metadata may not be retained, so keep an untouched original.
Review the calculated dimensions for every image, especially in a batch with portrait and landscape files. Enlarging can make raster images look softer; use the no-enlarge option when you only want smaller copies.
The best option depends on whether the destination asks for exact dimensions, a proportional reduction or a consistent maximum size across mixed images.
Choose pixels when a website, marketplace or form gives a maximum width or height. Enter one side and keep the aspect ratio on for a proportional result. If you enter both sides, the tool fits every image inside that box without cropping it.
Percentage applies the same relative change to every file, even when their original dimensions differ. A 50% setting halves the width and height of each image. It is useful for making a quick lighter copy of an entire folder while preserving every image’s shape.
A value above 100% or dimensions larger than the original creates more pixels through interpolation, but it cannot recover missing detail like AI super-resolution. Resizing is also different from compression: smaller dimensions often reduce bytes, while compression changes how those pixels are encoded.
No. Files are decoded, resized and packaged entirely in this browser. Image data is not sent to FreeToolsWeb.
Yes. The tool resizes all frames and preserves their timing. Very large animations are limited to protect browser memory.
Often, especially when making images smaller, but dimensions and file compression are different. The final byte size depends on the format and image content.
Yes. Safe SVG markup remains vector; the tool updates its width, height and view box information when needed.
