1 MB — one million bytes — is the round cap that shows up when a form allows a large photo or a scan and still refuses a camera original. This page sets the target to 976 KB: the compressor counts each KB as 1024 bytes, and 976×1024 is 999,424, under that million. The tool only lowers quality until the file fits and, if minimum quality is still too big, it scales the dimensions down too.
A multi-megabyte photo at 1 MB does not pick up the washed-out look of a 100 KB cap, so it works for a short portfolio, a case file or an application that includes an image. Drop several at once: each card shows the size achieved, and you download them individually or as a ZIP.

Frequently asked questions
Why does the field say 976 and not 1000?
The compressor counts in KB of 1024 bytes, the same unit as the 20, 50, 100 and 200 KB pages. At 1000 the file can reach 1,024,000 bytes, and a form capped at 1,000,000 would reject it. 976 KB is 999,424 bytes, so it fits. You do not need to change it.
Is 1 MB enough for a one-page scan?
Yes: a megabyte fits a single scanned page at a resolution that keeps the text sharp, which is what many registries and calls for applications ask for. If the source has several pages, export each one as an image and compress them in the same batch.
Are my documents uploaded to a server?
No. All processing happens inside your browser using the Canvas API: your files never leave your device, there are no upload queues, and the tool even works offline once the page has loaded.
