How to use this tool

Choose a JPEG, PNG or WebP file, or drag it onto the drop area.
Check the target size (currently 70 KB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool lowers the quality first, then reduces the dimensions step by step if the file is still too large.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you compress Image to 70 KB

At 70 KB most photographs hold on to good detail at screen resolution. A JPEG portrait may keep much of its resolution, and small printed text in a scanned document is much more likely to remain legible than at 30 or 40 KB. It is also a practical choice when a form says 'under 100 KB' but you want a little safety margin and sharper output than a heavy squeeze would give. Document scans, which combine white backgrounds with sharp text, tend to compress well as JPEG, while PNG scans only shrink by losing pixels. For text-heavy images, check the preview at full size; if letters look fuzzy, reducing the dimensions slightly often reads better than pushing the quality lower.

Seventy kilobytes is a comfortable middle ground for document photos and web thumbnails where detail still matters. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

Keep the target at 70 KB or adjust it with the size field. Use JPEG output for photographs and scans. For screenshots with flat colours, PNG may remain a good fit, but compare sizes before choosing.

Accepted input: JPEG, PNG and WebP (WebP depends on your browser). HEIC and AVIF are not supported. PNG is lossless, so it can only get smaller with fewer pixels unless you choose JPEG or WebP output.

Practical uses

Document and ID scans for online submissions
Web thumbnails and product images with a modest budget
Email-friendly photos when you want to keep text readable

Tips for a smaller file

For scans, check that small text is still readable in the preview.
Crop scanner margins and shadows before compressing.
Use JPEG output for scans rather than PNG.
Leave headroom if the portal says 'under 100 KB'.

Frequently asked questions

Is 70 KB enough for a scanned document?

Often yes for a single page at moderate resolution, but it depends on the scan. Check the preview to confirm that small text stays readable.

Does the tool keep my image's format?

By default, yes. You can switch the output to JPEG or WebP if that gives a smaller or better-looking result.

Can I get an exact 70 KB file?

Not exactly. The tool aims at or just below 70 KB and shows you the true size after processing.
