Batch Image Resizer

Resize pictures to fit, not to stretch

This batch image resizer changes pixel dimensions while keeping each picture’s original proportions. Set a maximum width, a maximum height, or both. DraftFort fits every image inside that boundary without cropping it. The default 1920 × 1080 box is a practical starting point for screen sharing, web content and ordinary presentations, but it is not forced on you.

Everything runs in the browser. The tool does not upload a photo before it can resize it, and it does not require an account. Your original files remain unchanged; the browser creates new downloads with -resized filenames.

How to resize JPG, PNG or WebP images

1. Add one image or a batch. Choose up to 25 supported files from your phone or computer.
2. Set the bounding dimensions. Enter the largest allowed width and height in pixels. Use 0 when one side should remain unrestricted.
3. Choose the output format. Keep every original format, or make the whole batch JPG, PNG or WebP.
4. Leave enlargement off for normal use. A smaller image then stays at its original size instead of being scaled up.
5. Resize and review. Each row shows the new pixel dimensions and file size. Download one result or all results in a ZIP.

How the size box works

The width and height fields are maximums, not a command to force every image to the same shape. That distinction prevents distortion.

The examples preserve aspect ratio and do not crop. If a platform requires an exact square, resizing alone is not enough: that job also needs cropping or padding, which this tool deliberately does not apply without your instruction.

Pick an output format intentionally

• Keep original is the safest resizing default. JPG remains JPG, PNG remains PNG and WebP remains WebP.
• JPG is useful for ordinary photos and broadly compatible sharing. Any transparent area is placed on white because JPG has no transparency channel.
• PNG preserves transparency and uses lossless encoding, but photographic files can be much larger.
• WebP supports transparency and often gives compact web-ready output, but check the requirements of older publishing or office systems.

Changing a JPG to PNG cannot restore detail already discarded by JPEG compression. For deliberate format changes, use the image converter. When file size—not dimensions—is the main constraint, use the image compressor.

What private browser resizing changes

DraftFort decodes the visible image, draws the resized pixels to a local browser canvas and encodes a new file. That process does not carry EXIF, GPS, camera or other embedded metadata into the result. This can be useful before ordinary sharing, but it also means the output is not an archival replacement for the original photograph.

Keep original files for professional print, evidence, medical imaging, exact colour-profile work or any process that depends on metadata. The resizer is for convenient derivatives, not for changing the authoritative source.
