Resize an image to 1 MB
Compress a large photo toward a 1 MB file size online for free. The editor searches for a quality setting that fits while retaining your chosen dimensions. Preview the output before downloading, and reduce the width if needed. Your original stays unchanged, with no image upload or signup required.

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.

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.
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?
The quality search keeps your selected dimensions. If it cannot reach 1 MB, the editor shows that the output is still over target and you can reduce the width.
Always check the final dimensions and file size before submitting.
