Compress JPEG to 70 KB
70 KB is a comfortable size for listing thumbnails and small web images — sharp, but light enough for pages that show many at once. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 70 KB?
70 KB is a common upload limit for profile photos and document uploads with a strict limit. At that size a JPG photo can be about 650×490 pixels at medium quality.
About 650×490 px fits
At medium quality a detailed JPG photo of roughly 650×490 pixels lands under 70 KB; at high quality about 460×340.
Typical use
70 KB limits are common for profile photos and document uploads with a strict limit.
51× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 51×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 70 KB, quality is fine for small display. Good for thumbnails, profile photos and forms.
Scans and documents
A scanned A4 page of about 790×1120 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
70 KB is measured as 71,680 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Thumbnails for pages with many images
Category pages, search results and galleries can show 20–50 images at a time. At 70 KB each, fifty thumbnails are about 3.5 MB — heavy, but workable; at 300 KB each they would be 15 MB.
Pixel guide: about 620 pixels wide, sharp in a 300-pixel slot on high-DPI screens.
Consistent sets. Resize every thumbnail to the same pixels first (for example 600×600), then compress the batch here.

Frequently asked questions
Is 70 KB good for website thumbnails?
Yes for mid-size thumbnails around 300 pixels on screen. Very small thumbnails can be lighter still.
How many pixels fit in 70 KB?
For a detailed JPG photo, about 650×490 at medium quality or 890×660 at low quality. Simple graphics and scans can be much larger.
What quality will a 70 KB photo have?
Fine for small display. Good for thumbnails, profile photos and forms. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 70 KB the same as 70,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 70 KB is 71,680 bytes. The tool uses the same count, so a file it marks as under 70 KB is accepted.
Should I use JPG or WebP for 70 KB?
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 70 KB?
Very large or detailed images may not reach 70 KB by quality alone. Resize it first (for example to 650 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.
