Name the TFileNameEdit as SourceFileEdit.ĭraw a TGroupBox. Change the Filter property of the TFileNameEdit to: You can also add a TLabel and set its caption appropriately. We will open our image file in this component. But anyways, let's get on with it.Ĭreate a new Application Project (Project->New Project->Application->OK).ĭraw a TFileNameEdit in the form (from Misc tab). Now, I have tried to only use TJPEGImage to compress JPEG to JPEG. The quality should be a value between 1 and 100.Īfter assigning the picture to TJPEGImage, when we try to SaveToFile or SaveToStream, it will give us the compressed jpeg image. This way we are taking the most crude image and then convert it to JPEG.) We also set the compression level for the quality. (We could have chosen png or jpeg, but bitmap is uncompressed. We would also initialize the TJPEGImage and assign the Bitmap instance of our loaded picture from TPicture. We would have to load our image into the TPicture. If we want to load, for example, BMP, PNG, GIF, TIFF etc. TJPEGImage cannot load any file other than. Jpg.SaveToFile(Utf8ToSys('C:\test3.jpg')) Jpg.CompressionQuality:=70 // Enter desired quality (1~100)

To compress any supported image formats to Compressed JPEG you can use this simple code snippet: Cool right! We could forget photoshop for just this simple task! May be even add some custom code to add frame or watermark of a website/company logo. And may be we could add cropping feature in it and may be even pasting from clipboard.
We can easily utilize that feature and use it to make our very own JPEG compressor.

Lazarus / Free Pascal has a handy TJPEGImage class which has the ability to open JPEG files as well as compress them. How if we could have our own program do it for us? It would be time-saving and fun. But I personally end up opening Photoshop and saving the image from there and optionally cropping it. Because people can't load 1mb~ images in a website or blog. Very often we find out that we take a screenshot and we look for a tool to compress it in a snap. Sounds exciting, doesn't it? It can convert and compress from any other image formats too!
