- Compress on this device, check the actual size, then download.
Worked example: a portfolio JPG that a host caps at 1 MB
Resize a 24-megapixel original to the portfolio’s max width (often 2000–2500 pixels), then compress that copy to 1024 KB as JPG or WebP. The preview should stay close to the resized look. If the host counts MiB strictly, the result will be at or under 1,048,576 bytes because the tool aims below the typed target.
What this job is for
At 1 MB you can usually keep useful pixel dimensions. Prefer this target when the destination shows the image large and you have already resized to something near the display size. Do not use 1 MB for a 200-pixel thumbnail.
Useful limits
One megabyte is still too large for many email systems. Use 100–200 KB for attachments. Keep print masters uncompressed.
The live tool behind this page is Image Compressor. It is the same local engine as the rest of Image Cosmos.
Frequently asked questions
Is 1 MB the same as 1024 KB?
This page uses a 1024 KB target, which is the conventional binary megabyte. The finished file should be slightly under that.
Should I pick 1 MB or 500 KB?
Use 1 MB when the image is shown large and the host allows it. Use 500 KB for ordinary CMS entries.
Does Image Cosmos store the 1 MB file?
No. The download exists only as a temporary browser link.
