The target is preset, so this takes three steps — plus what to expect at 850 KB.
Click upload or drag and drop any JPEG, PNG, WebP, SVG, or GIF file from your device.
This page is preset to 850 KB, so there is nothing to type. Choose JPEG or WebP output for the most efficient result at this size.
Press compress and check the result against your original in the slider. Roughly 4000 × 4000 px is the realistic pixel budget at 850 KB — download when it looks right.
Compress from the camera file, not from an already compressed copy. An archive made from a degraded source locks that degradation in permanently.
Compress the bulk of a library and keep true originals for the small number that are genuinely important. Blanket policies waste either space or quality.
Free online tools for every image task.
Compress images without losing quality.
Resize images to exact dimensions or by percentage.
Convert between JPEG, PNG, WebP, and other formats.
Crop images to any size or predefined aspect ratio.
Compress multiple images at once and download as ZIP.
Rotate images by any angle or flip horizontally/vertically.
What 850 KB is actually for, what it can hold, and how to get there without wasting quality.
850 KB is an archival compromise. Camera originals at 25 MB each are the ideal thing to keep and often the impractical thing to keep, particularly across years of photographs.
At this size you retain enough for future printing and cropping while cutting storage by roughly 95% against the original.
Long-term personal photo archives, family collections, records where originals are impractical to store, and backup copies of a working library.
Roughly 16 megapixels of usable data — enough to print at A4, crop substantially, and still have a genuinely useful image years later.
