1Upload the JPG images you want resized — work from the largest original you have rather than from a copy you already shrank once.
2Set the new size: for an image, a width and height in pixels with an optional aspect-ratio lock; for a video, one of the preset sizes from 1920x1080 down to 640x360.
3Start the resize; the picture is scaled to the size you chose.
4Download the resized JPG file.
Resize JPG FAQ
Does the source format affect the result of a resize?
+
It does. JPG stores 8-bit RGB through a lossy DCT with 4:2:0 chroma subsampling by default, so fine red text and hard edges are the first things to soften. That is what decides whether shrinking the file is purely a question of pixels or also a question of re-encoding.
Is there anything specific to JPG I should watch for?
+
Yes — every save re-runs the quantiser, so repeatedly editing and resaving a JPG compounds generation loss even if you never lower the quality slider. Worth checking before you resize a file you will not be able to regenerate.
Can I keep the aspect ratio, or force exact dimensions?
+
Both. Lock the ratio and one dimension is derived from the other, which is what you want almost always. Unlock it and you get exactly the numbers you typed, at the cost of stretching — useful for a fixed slot, wrong for a photograph.
What happens to EXIF and colour profile data?
+
It depends on the tool. Compression strips EXIF and the embedded colour profile to save space, while edits such as resizing or rotating can keep them. There is no setting on this page to choose, so check the file with a metadata viewer before publishing it if location data matters.
What can I upload to Resize JPG?
+
Anything in the lossy raster family — JPG, JPEG, JFIF and WebP — plus the lossless formats (PNG, BMP, TIFF) if you want to mix them in one batch. The format is read from the file header, not the extension, so a photo saved with the wrong suffix still goes through.
Is there a file size limit on Resize JPG?
+
Yes: free accounts process images up to 5 MB each, which covers essentially every camera JPG and phone photo; the work is done by libjpeg-turbo and libwebp, the same libraries a desktop editor links against. Larger files are the one thing the free tier will stop you on, and the limit is per file rather than per batch.
Why would a modern-format site run Resize JPG?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Resize JPG is on the same upload and the same account so those questions get answered in one place.
Once Resize JPG has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
