Frequently asked questions
How do I improve photo quality online?
Upload the photo, use Auto enhance or adjust brightness, contrast, color and sharpness, then download the enhanced image.
What does the auto correction do?
It stretches each color channel so the darkest and brightest tones use the full range. This removes haze and color casts and makes photos look clearer.
Will my photo lose quality?
No. The image keeps its original resolution. JPG photos are saved at high quality and PNG images stay lossless.
Which formats are supported?
JPG, PNG, WEBP, GIF and BMP. You can keep the original format or save as JPG or PNG.
Are my files uploaded to a server?
No. PDFFlow processes your files entirely inside your browser using JavaScript. Nothing is uploaded, stored or seen by anyone else, and the result is created on your own device.
Is this tool free?
Yes. Every PDFFlow tool is free to use with no sign-up, no watermark added to your files and no daily task limit.
