File size mode works at up to 2290 pixels on the long side, then searches for the highest quality that fits. Our five test photos landed at quality 91 to 96, the largest at 1,046,025 bytes.
What to expect at this size
These are measured figures, not estimates. Five photographs were run through this page's own engine and the results written down.
The range is what varies between an easy photograph and a hard one: a flower against a blurred background compresses far better than a street full of signage.

Which forms ask for 1 MB?
Each form below states 1 MB as the most it accepts. Where a form also states a minimum, this page does not check it. The form's own page keeps the file inside the whole range.

Why do forms ask for this size?
A 1 MB target can make a large photo easier to share or fit an upload limit. The result depends on resolution, detail and output format.
This preset uses 1,048,576 bytes; if your destination means 1,000,000 bytes, choose a lower custom target and check the final size.
What is the difference between resizing and compression?
The main difference between resizing and compression is the measurement you change. Resizing changes width and height in pixels. Compression reduces file size in bytes.
A photo can have the correct dimensions and still exceed an upload limit, so check both requirements.
If you need both, set the dimensions first and then adjust quality or the file size target. Work from the original and download once to avoid repeatedly recompressing a saved JPEG.
PNG has no quality setting, so a PNG over the target is reduced to fewer colours instead, keeping as many as fit. The meter shows the count.
Screenshots and graphics usually survive this with no visible change. A photograph needs many colours, so bands of flat colour can appear at a small target, and JPEG is then the better format.
What happens to your photo?
Your selected photo is processed in your browser, without an image upload to a server. The page may download code and codecs needed for editing.
Save your result before closing the tab; unsaved edits are kept in memory rather than in an online account.
Common questions
Why is my camera photo so much bigger than 1 MB?
A camera photo can contain millions of pixels plus metadata, and detailed scenes take more data to encode. Lowering quality or dimensions can reduce its size.
Keep the original for later editing, since a smaller lossy export discards some information.
Does this reduce the dimensions as well?
Only if the long side of your photo is over 2290 pixels. File size mode works at that size or your photo's own, whichever is smaller, and then lowers the quality until the file fits.
To keep more pixels, choose Pixels and lower the quality yourself. The Download button shows the file size before you save.
