Photo files will not open
Make sure the file is in JPG, PNG, or WebP format. HEIC from iPhone depends on browser and operating system support; if it will not open, export the photo to JPG first using the Photos app or try another browser that supports it.
Try opening another photo to make sure the problem is not with the tool. Reload the page if the display stops responding. The editor cannot repair files that are corrupted, truncated, or incompletely downloaded.
Photo is too large or processing gets stuck
Processing happens on your device, so your browser's memory capacity matters. Close other heavy tabs, use a photo with smaller dimensions, or continue on a desktop for very high-resolution images.
Do not close or reload the tab while processing is running. If the progress bar stalls for a long time, wait a moment, then try again with the same file after reloading the page.
Which formats are supported?
The tools accept JPG, PNG, and WebP. The output format follows the choice on each tool, usually JPG, PNG, or WebP. Use PNG for logos, sharp text, and transparent backgrounds; use JPG for ordinary photos that need a smaller file size.
- JPG does not support transparency. Transparent areas are filled with the background color on export.
- WebP offers a small file size with good quality, but not every older app can open it.
- HEIC and some camera-specific formats may need to be converted on your device first.
Colors or output quality change
Small color differences can occur because browsers do not always preserve a photo's color profile. For the most consistent results, use photos with an sRGB profile and compare the result at 100% zoom.
JPG and WebP compression discards some detail to reduce file size. If quality matters more than size, choose PNG or increase the quality setting before downloading.
Offline use and the PWA
After a page has been opened while online, a service worker stores the app shell and main assets. You can reopen saved pages when the connection drops, and tools that have already loaded can still process photos from your device.
Pages you have never visited may not be available offline. If you see an offline page or an unstyled layout, connect to the internet and reload once so the cache can update.
To install it as an app, use your browser menu, such as Install app or Add to Home Screen. On iPhone, open the Share menu in Safari and choose Add to Home Screen. A PWA requires HTTPS or localhost, and clearing site data will remove the offline cache.
Edits are lost after refreshing
EditFotoOnline does not save projects automatically and has no cloud storage. Changes live only in the tab's memory until you press the download button.
Download the result before closing the tab, reloading the page, or switching devices. Also keep a copy of the original photo so you can repeat the edit if needed.
The app feels slow or will not appear
Update your browser to the latest version, disable extensions that restrict JavaScript, then try incognito mode to confirm there is no extension conflict. Make sure JavaScript and site storage are not blocked.
If only one page is affected, go back to the home page and open the tool from the list. For issues that persist, note the error message and the steps you have already tried.
Still need help
Send a report through the contact page. Include your device type, browser and version, the tool name, and a brief description of the steps that led to the problem. A screenshot of the error message helps, but do not send personal photos that are not needed.
