The Photo Editor App Overview
The Photo Editor is an application that allows you to adjust PNG files without downloading any software on your device. Our app is designed to correct the brightness, contrast, hue, saturation, and vibrancy of PNG images and download the result in PDF format.
Adjust the brightness, contrast, hue, saturation, and vibrancy of your image using the appropriate sliders for:
- Applying brightness adjustment filter changes the brightness level of the image.
- Applying contrast adjustment filter changes the degree of various colors between the elements that form a photo.
- Applying Hue adjustment filter subtly changes the color of an image. Saturation affects the intensity of colors evenly, increasing the power of each color in the photo.
- Applying Vibrancy adjustment filter subtly enhances most colors in your image. Specifically, it emphasizes parts of the image that are not colorful enough.
After editing your PNG file, you can download it directly to your device as a PDF file.
One of the features of our Photo Editor is Photoshop®-like image processing that treats images as a layered PSD file.
Once you have added a PNG image for editing, it will be converted to a PSD image using the original image as the background layer. The added filters is applied as an adjustment layers over the background layer with the original image in the order of adding.
Please note that the order in which you add adjustment effects affects the final result.Saving the result in a PDF file format renders the raster file as if it was rendered in Photoshop® and then exported to a raster file format.
Why save PNG files as a PDF?
Although PDF and PNG have the same quality, we recommend using PNG for web images and PDF to print images. PNG quality is not good enough for printing. The lack of transparency and lack of interaction makes PDF files unsuitable for the web.
PNG (Portable Network Graphics) files use lossless data compression to reduce the image to a usable size, which can be saved and opened from any browser. It was developed for transmitting images over the Internet. PNG supports palette images with 24-bit RGB or 32-bit RGBA colors, grayscale images, image transparency, and full-color RGB images without a palette.
PDF (Portable Document) is the standard for document sharing because it stores exact copies of files, including graphics and images. Compatible with both vector and raster images. The PDF format allows extra compression without sacrificing quality for faster uploads and downloads. One of the key features of PDF files is the ability to control access and permissions. PDF is a secure file format that allows adding passwords, watermarks, and signatures. PDF uses CMYK color mode coincident with the calibration of commercial printers.
Nevertheless, the PDF file format has drawbacks too:
- Does not support transparency.
- Not optimized for web browser windows.
- Scrolling or scanning pages are not supported as regular web pages.
Our app is a virtual instrument powered by Aspose.PSD. All files are processed with Aspose APIs, which are used by many Fortune 100 companies across 114 countries. Our API in .NET or JAVA is useful for developers and comes with great documentation, clear code samples, and an all-dev support team.
