Resize Image
Resize or convert a JPG, PNG or WebP — by pixels, percent or target size.
Resize Image changes an image's dimensions by pixels or percent, or aims for a target file size, and converts between JPG, PNG and WebP — honouring the photo's EXIF orientation and, by default, stripping its metadata. The result is measured on the output file; if a target size cannot be reached at acceptable quality the tool tells you rather than reporting a number it did not achieve.
Resize Image changes an image's pixel size, format or file size in your browser — free, with no account and no watermark. The image is processed on your device and is not uploaded to a server.
How to resize image — steps & common uses
What people use Resize Image for
People who need an image at a particular size — in pixels or in kilobytes — and would rather not install anything for it.
- Shrink a photo to fit an upload limit
- Convert HEIC-exported JPGs to PNG or WebP
- Resize a picture to exact pixels
- Strip location data from a photo before sharing
- Make a smaller image for a form
How to resize image
- Drop in a JPG, PNG or WebP; its real dimensions and orientation are read from the file itself.
- Choose what to change: exact pixels, a percentage, or a target file size in KB.
- Pick the output format and quality, and decide whether to keep the camera metadata.
- Download — the result reports the dimensions and byte count read back out of the file it produced.
Good to know: Metadata is stripped by default (a checkbox keeps it); a target size that cannot be reached is reported, not faked.
Questions about Resize Image 6
Are my files uploaded to a server?
No. UnboundPDF processes PDFs locally in the browser — documents are not uploaded to a server. We have no backend that receives, stores, or scans your files.
Can I aim for a particular file size?
Yes, for JPG and WebP: the quality is stepped down until the encoded file is at or under your target, and the result reports the size actually reached. If the target could not be met at the lowest quality, it says so rather than handing back a larger file quietly. PNG has no quality dial, so a size target is not offered for it.
Are sideways photos fixed?
Yes. A photo from a phone often stores its pixels sideways with an EXIF orientation tag saying which way is up. The tool works from the upright picture and writes the output upright, so it stays right even when the metadata is stripped.
Is my camera metadata kept?
No, unless you tick the box. The output is encoded fresh from the pixels, so EXIF — including any GPS location — is not carried over by default. Ticking the box copies the original's EXIF block into a JPG output.
Which formats can it read and write?
JPG, PNG and WebP, in either direction, subject to what your browser's own encoder supports. If the browser cannot encode a format, the tool says so instead of producing a broken file.
Does the printed size stay the same?
Where the source recorded a resolution, that figure is carried into the output, so an image intended for print at a given DPI keeps that intent even though its pixel count changed.

How your files are handled
The work runs on your own device, inside the browser tab — so there is no server to send your document to.
- Nothing is uploaded. We have no backend that receives or stores documents, so we cannot see your files during processing or after.
- Your device does the work. Large documents are handled in stages, pages are rendered as you reach them, and each job is checked against your device before it starts — so a long run takes longer on a phone than on a laptop, nothing is queued behind other people's jobs, and you can stop a run at any point without touching your original file.
- No account and no watermark. The output is a clean file you can use anywhere, with no sign-up and no hourly cap.
