Options and important limitations
Palette extraction samples a downscaled image and groups similar colors. Mostly transparent pixels are ignored; gradients may produce fewer distinct colors than requested. Pixel picking samples the full-resolution source.
The contrast ratio uses relative luminance for two solid sRGB colors. Thresholds shown are 4.5:1 for AA normal text, 7:1 for AAA normal text and 3:1 for AA large text. Passing one color comparison is not a full accessibility audit.
The exported JSON contains the displayed palette and the selected contrast colors. It does not include the source image, filename or image metadata.
Privacy and device safety
Files and entered content are processed locally. Helphonic checks access and records non-content operation metadata only. Download your results before leaving the page.
One source image is allowed per operation. Raster inputs and exports are limited to 16 megapixels and 8000 pixels per side. Administrative file-size limits may be lower.
Processing and privacy
Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation. Previewing and editing do not use an operation. Daily allowances reset at 00:00 UTC. Downloads of an already-created result do not count again.
If an operation cannot finish
Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.
If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.
Check the current limits
Allowances and per-operation limits can change. The Color Picker & Palette Extractor page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
