Compress and resize images
Make photos small enough to email or upload. Batch resize, set a quality, see the savings before you download.
Done
Open the network tab. It stays empty.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
How it works
- Drop the images you want to shrink.
- Set a maximum width or height, or a percentage, and pick a quality.
- Compare the before and after sizes, then download.
In your browser, not on a server
Resizing uses stepped downscaling on a canvas so text and edges stay sharp, and the browser encodes the result at the quality you choose. Everything happens in memory in your tab. Large batches are processed one image at a time so the page stays responsive on a phone.
Compared with upload-based tools: Image compressors that upload your photos limit you to a few files, a small size, or a watermark until you pay. This one has no counter to reset because there is no server to keep one.
Verify it yourself. Load this page, turn off Wi-Fi or switch to airplane mode, and run the tool. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
How much smaller will my images get?
A 12 megapixel phone photo (around 3 to 4 MB) resized to 2000 pixels wide at quality 80 usually lands between 300 and 600 KB with no visible difference on a screen. The result panel shows the exact saving per file.
Should I pick JPG, WebP or keep the original format?
Keep the format if you are unsure. Choose WebP for the smallest files that still look good in any browser. Choose JPG if the file has to open in older software. PNG stays lossless, so it only shrinks when you resize it.
Does resizing keep the aspect ratio?
Yes. The image is scaled so that neither side exceeds the limits you set, and the proportions never change.
Is metadata kept?
No. Re-encoding drops EXIF data, including GPS location, which is usually what you want before sharing. If you only want to remove metadata without changing pixels, use the EXIF remover instead.
