Resize Image

How Resize Image works

Enter a width, a height, or both. With Keep proportions ticked, the image is scaled to fit inside the size you give without being stretched; untick it to force exact dimensions. Or switch to Percentage to scale everything by the same amount, such as 50 percent.

JPG, PNG and WebP images keep their format; other formats are saved as PNG. JPGs are saved at 92 percent quality, which is visually identical to the original for photos, and transparent PNGs and WebPs keep their transparency.

Resizing uses your browser's own high-quality image scaling, so each image takes a moment and never leaves your device. Several images can be resized in one go, each with its own download button.

The resized file is named after the original with the new dimensions added, such as photo-1280x960.jpg, so it is easy to tell apart. Resizing a batch applies the same settings to every image: with Keep proportions on, portrait and landscape photos each fit inside the size you give without being cropped, so a mixed set of photos all come out within the same bounds. Only the first frame of an animated GIF is kept, since the result is a still image.

Resize Image options explained

When to use it

Resize images to meet an upload limit on a job portal or marketplace, to make photos the right size for a website or email, to fit social media dimensions, or to shrink phone photos before sending them.

Scaling down is always clean; scaling up cannot add detail, so enlarged images look soft. For web pages, a width of 1200 to 1920 pixels covers almost every layout, and the image compressor can shrink the file further.

About the image resizer

Resizing uses the canvas built into your browser with its high-quality smoothing, the same scaling browsers use to display images, so no extra code has to download. It is fast: a phone photo resizes in well under a second. The size of the file you get depends on both the new pixel dimensions and the format: halving the width and height leaves roughly a quarter of the pixels, so a photo usually ends up at around a quarter of its size. To shrink files further without changing their dimensions, use the image compressor, and to change format at the same time, use one of the image converters.

Resize Image troubleshooting

"Enter a width, a height or both"

In pixel mode at least one of the two boxes needs a number. Leave the other empty to keep the proportions automatically.

The image looks stretched

Keep proportions was off and the new size has a different shape. Tick it and resize again from the original.

A HEIC photo will not load

Browsers other than Safari cannot read HEIC directly. Convert it with HEIC to JPG first, then resize the JPG.

How to use Resize Image, step by step

1. Press "Choose images" or drag files onto the box.
2. Set the options if you need to; the defaults suit most uses.
3. Press "Resize". The work happens on your device.
4. Save the result with its download button.

Is it safe to do this online?

With most online tools, "online" means your file is uploaded to a company's server, processed there and kept for a while before it is deleted. Here it is not. The page downloads the tool's code to your browser, and your file is read and processed inside the tab on your own device. It is never sent to TapToConvert or anyone else.

You can check this yourself: once the page and its engine have loaded, turn off Wi-Fi and the tool still works. That also means there is no queue, no daily limit and no file size cap set by a server; the only limit is the memory your browser gives a single tab.
