Compress JPEG to 1 MB
Get a JPG under 1 MB. This page always saves JPEG — even if you drop in a PNG or WebP — and finds the highest quality that fits under 1 MB. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 1 MB?
1 MB is a common upload limit for blog images, large web graphics and attachments. At that size a JPG photo can be about 2520×1890 pixels at medium quality.
About 2520×1890 px fits
At medium quality a detailed JPG photo of roughly 2520×1890 pixels lands under 1 MB; at high quality about 1760×1320.
Typical use
1 MB limits are common for blog images, large web graphics and attachments.
3.5× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 3.5×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 1 MB, quality is very good. There is room for a sharp, full-screen photo.
Scans and documents
A scanned A4 page of about 3040×4300 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
1 MB is measured as 1,048,576 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

A JPG under 1 MB, every time
Many forms ask specifically for JPG/JPEG under 1 MB. Two things can go wrong: the file is too big, or it is the wrong format. This page fixes both — the output is always JPEG, and it is compressed to fit.
Transparent PNGs become JPG with a white background, because JPEG cannot store transparency.
1 MB at full phone resolution is possible with moderate compression. If the result looks soft, reduce the width to about 2000 px on the Resize tab.

Frequently asked questions
Can I upload a PNG and get a 1 MB JPEG?
Yes. This page converts every image to JPEG while compressing, so a PNG, WebP or BMP comes out as a JPG under 1 MB.
How many pixels fit in 1 MB?
For a detailed JPG photo, about 2520×1890 at medium quality or 3410×2560 at low quality. Simple graphics and scans can be much larger.
What quality will a 1 MB photo have?
Very good. There is room for a sharp, full-screen photo. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 1 MB the same as 1,000 KB?
Most forms count 1 MB as 1,024 KB (1,048,576 bytes). The tool uses that count, so the result fits under the limit.
Should I use JPG or WebP for 1 MB?
JPG is accepted everywhere and is the safe choice for forms. WebP holds about 30% more detail at the same size, ideal for websites that support it.
Why is my file still over 1 MB?
Very large or detailed images may not reach 1 MB by quality alone. Resize it first (for example to 2520 pixels wide) with the resizer, then compress again.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and it will still work.
