How it works
Add one or more images, choose how to resize them and download the results. Everything happens in your browser: your images are never uploaded to a server.
- Percentage scales every image by the same amount, e.g. 50% halves the width and height.
- Width or Height sets one side in pixels and keeps the proportions.
- Fit within a box makes each image as large as possible inside the size you set, without stretching or enlarging small images. Ideal for batches of mixed portrait and landscape photos.
- Exact size forces the dimensions you enter, which can stretch the image.
Large reductions are done in several steps for sharper results. Download images one by one, or all at once as a ZIP file.
Frequently asked questions
Are my images uploaded?
No. The images are decoded, resized and saved by your own browser. Nothing is sent to Oxenly or anyone else, so it also works for private photos and documents.
Does resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging can't add detail, so upscaled images look softer. For JPG and WebP, the quality slider controls compression; 85–92% looks identical to the original for most photos.
What sizes should I use for the web and social media?
For websites, 1600–2000 px on the long side is plenty for full-width photos. Common social sizes are 1080 × 1080 (square posts) and 1200 × 630 (link previews).
Is photo metadata kept?
No. Resized images are re-encoded without EXIF metadata, which also removes camera details and GPS location. Orientation is applied to the pixels, so photos stay upright.
Which formats are supported?
You can open JPG, PNG, WebP, GIF (first frame), AVIF, BMP and SVG, and save as JPG, PNG or WebP. HEIC photos from iPhones aren't supported by most browsers; export them as JPG first.
