How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
70 KB is a useful size for a single scanned page. It is large enough to keep small print readable, and small enough to upload through the slowest form on the internet.
The tool lowers quality in steps and keeps the best result at or below 70,000 bytes. For a scan, switching the format to WebP or PNG often gives a cleaner page at this size than JPEG does.
A scan of text is mostly white paper with thin dark lines. Those lines are what the reader needs, so the whole job is to keep the edges sharp while the white costs almost nothing.
Scanning for a small file
Scan at 150 to 200 dots per inch, not 600. A page scanned at 200 dpi is about 1,650 by 2,300 pixels, and that is more than enough to read. Higher resolution makes the original bigger without making the final 70 KB look any better.
Black and white or grey
Text pages do not need colour. Switching to black and white in the editor removes the colour channels, and the same 70 KB then goes entirely into the shape of the letters. A coloured stamp or logo is the exception, so keep colour for those.
Photos at 70 KB
For a photograph, 70 KB supports about 750 pixels square. That is a clean picture for a web page, with fine detail on a face and clear background shapes. It is also a reasonable size for a product photo on a white background.
Multi-page documents
If a form wants one image per page, compress each page to 70 KB separately, and check that the last line of each one is still legible. A document of five pages then weighs about 350 KB in total.
Checking legibility
After you compress a scan, view it at the zoom a reader will use, usually the full width of the screen. Read the smallest line out loud. If you stumble over it, raise the target to 100 KB or scan at a slightly higher resolution, then compress again.
Faint pencil and thin pen strokes are the first to vanish at small sizes.
Receipts and screenshots
Receipts and screenshots of settings pages compress well at 70 KB when saved as PNG or WebP. They have large flat areas and fine text, which is the case those formats handle best. Crop the screenshot to the part that matters to save even more.
Take care not to cut off the page number or a signature at the bottom.
Receipts and screenshots
Receipts and screenshots of settings pages shrink well at 70 KB when saved as PNG or WebP. They have wide flat areas and fine text, which those formats handle best. Crop the screenshot to the part that counts and you save more.
Make sure the date and the amount stay inside the crop.
Frequently asked questions
Will small text stay readable at 70 KB?
It does when the scan is clean and the pixel size is large enough. Check the smallest line at full size.
PNG or JPEG for a scanned page?
Try PNG or WebP first, since they keep sharp edges. Fall back to JPEG if the file will not fit.
Can this make a PDF?
No. This page writes an image. There is a separate tool for turning images into a PDF.
Is the text searchable after compressing?
No. The result is a picture. Searchable text needs OCR software, which this page does not run.
Will blurry text become sharp?
No. Compression cannot add detail that was not captured. Rescan or retake a sharper original first.
