Understand the safeguards →What this tool does
Start with small values such as 10 to 20, run the edit and compare the preview with your photo. 0 leaves a setting unchanged, and negative numbers reduce brightness, contrast or color. Warmth below 0 gives a cooler, bluer look.
Example input
Select a supported local file; the visible settings are a starting example.
What to expect
Review the generated local preview or downloadable copy before using it.
Questions people often ask.
Does photo editor upload my data?
No. This tool processes your input inside your browser. Your text and files are not sent to an application server. The static host receives page and asset requests; see our privacy explanation.
Is this tool free for work and study?
Yes. No account, paid API, usage subscription or watermark fee is required. You remain responsible for your content rights and checking results. Hosting providers and their free tiers are separate from this open-source software.
What should I check before relying on the result?
PNG, JPEG or WebP only. Maximum 20 MB and 12 megapixels. The result is a new copy made on your device; your original file is not changed. Review important outputs against the source, especially financial, legal, identity, medical and research calculations.
Will editing reduce my photo quality?
Every save creates new pixels. PNG keeps them exactly, while JPEG and WebP save space with a small, usually invisible loss. Keep your original and make each edit from it, rather than editing the same copy again and again.
Should I choose JPEG, PNG or WebP?
Choose JPEG for photos you share or upload, PNG for screenshots, logos and images with transparent areas, and WebP for small files on modern websites. Where a Save as option appears, "Same as original" keeps the format you uploaded.
How large can my image be?
Images up to 20 MB and 12 megapixels work, which covers photos from most phones. Resize very large images first.
