Compress an image to 60 KB
To get an image under 60 KB, PixelFit aims at 60,000 bytes or less, so forms counting 1 KB as 1000 or 1024 bytes both accept it. Estimated from our measured encodes, that is about 557 × 417 pixels for a 4:3 photo at quality 75, or 634 × 791 for a portrait.
Under 60 KB
JPG · under 60 KB (at most 60,000 bytes) · original pixel size · white background
PixelFit aims at 60,000 bytes or less, so the file passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

What 60 KB means in bytes
60 KB is 61,440 bytes when 1 KB = 1024 bytes (60 × 1024) and 60,000 bytes when a server counts 1 KB = 1000 bytes. The 1,440-byte gap matters only near the limit. PixelFit aims at 60,000 bytes or less and prints the exact byte count, so you can compare it with the form.
60 KB is 0.059 MB; 170 such files fit in 10 MB. Uncompressed, the 557 × 417 photo that fits here would need 680 KB of raw pixels, so JPEG at quality 75 packs it about 12 to 1.

A 12 MP phone photo at 60 KB
Our 12 MP landscape sample (4032 × 3024) is about 4.15 MB at quality 90, 73 times the 60 KB budget; even quality 30 leaves 1.26 MB (extrapolated from encodes up to 3,000 px). So the pixels must go down too.
At about quality 75 it fits 60 KB near 557 × 417 (0.23 MP, 2 % of the original pixels). Quality 60 allows 643 × 482; quality 90 needs 435 × 326.
JPEG quality for fixed pixel sizes under 60 KB
When a form fixes the pixels, only quality can move. Highest quality (of 100) that keeps each size at or under 60,000 bytes:
| Pixel size | Measured on | JPG | WebP |
|---|---|---|---|
| 413 × 531 (35 × 45 mm at 300 DPI) | portrait photo | quality 91 (54.7 KB) | quality 95+ (54 KB) |
| 600 × 600 (2 × 2 inch at 300 DPI) | portrait photo | quality 84 (58.6 KB) | quality 91 (56.6 KB) |
| 800 × 600 (4:3 web photo) | landscape photo | quality 33 (57.8 KB) | no: fewer pixels needed |
| 1080 × 1080 (square social post) | landscape photo | no: fewer pixels needed | no: fewer pixels needed |
| 1200 × 1600 (3:4 portrait upload) | portrait photo | no: fewer pixels needed | quality 48 (58.1 KB) |
| 1240 × 1754 (A4 page at 150 DPI) | scanned typed page | no: fewer pixels needed | no: fewer pixels needed |
Measured JPEG files either side of 60 KB
Real encodes from our test set at quality 75: the largest file that stays under 60,000 bytes and the smallest that goes over.
| Image | Largest under 60 KB | Smallest over 60 KB |
|---|---|---|
| Head-and-shoulders portrait | 480 × 600: 39,317 B | 641 × 800: 60,900 B |
| Outdoor landscape (12 MP phone photo) | 500 × 375: 48,064 B | 600 × 450: 69,996 B |
| Scanned typed document page | 477 × 600: 48,445 B | 637 × 800: 81,646 B |
| Handwritten letter with signature | 1000 × 822: 59,731 B | 1200 × 987: 80,051 B |

JPG, WebP or PNG at 60 KB
At quality 75, WebP holds 591 × 443 of the landscape photo in 60 KB, JPG 557 × 417: 13 % more pixels. Portrait gain: 142 %. Typed page gain: 59 %. A moderate gain for the landscape photo at 60 KB, a large one for portraits and typed pages: where WebP is accepted, use it for those. Many portals accept only JPG/JPEG, so this page starts in JPG.
A full-colour PNG is lossless, so its size follows the content. In 60 KB it holds a flat graphic of 1,259 × 881 pixels but a photo of only 199 × 149, against 557 × 417 as a quality-75 JPG. Reducing a PNG to a palette of up to 256 colours (PixelFit does this when a PNG must shrink) helps graphics far more than photos.
Which uploads fit comfortably in 60 KB
2 of the 6 sizes above keep quality 75 or better under 60 KB (413 × 531, 600 × 600); 3 miss even at quality 30 (1080 × 1080, 1200 × 1600, 1240 × 1754). At 557 × 417, quality 90 costs 64 % more bytes than quality 75.
A typed page reaches 626 × 786 at quality 60 in 60 KB, about 67 DPI if it is an A4 sheet.

Frequently asked questions
How do I compress an image to 60 KB?
Drop it into the tool here, preset to 60 KB. It searches JPEG quality (at most 8 encodes per pixel size), then scales pixels down if needed, until the file is 60,000 bytes or less. A 4:3 photo typically lands near 557 × 417 at about quality 75.
How do I compress an image to less than 60 KB without losing quality?
Give up pixels before quality: at quality 75, 60 KB holds 557 × 417 of a photo and 634 × 791 of a portrait; quality 90 at 557 × 417 costs 64 % more bytes.
Is 60 KB 60,000 or 61,440 bytes?
Both readings exist: 61,440 bytes (1 KB = 1024) or 60,000 bytes (1 KB = 1000). 60,000 bytes or less passes both.
Can I compress a PNG to 60 KB?
Yes, but a full-colour PNG photo stays big: about 199 × 149 pixels in 60 KB, versus 1,259 × 881 for a flat graphic. As a JPG the photo reaches 557 × 417.
What pixel size fits 60 KB?
At quality 75: a photo 557 × 417, a portrait 634 × 791, a typed page 537 × 674.
