1. General Questions

Why are there both an online service and a desktop application?

The online tool has limited maximum resolution, and only a few settings available. These restrictions are lifted in the Desktop Resizer application. A great amount of tweaking is possible, and it's all on your computer.

Can I use Reshade for printing?

Yes, this is one of the main uses for reshade. The printed images look even better than on screen. Reshading creates sharp textures and clear edges maintaining the original image details.

Why not use Photoshop?

First Photoshop costs a lot. Second, you need to be an advanced user and have a decent amount of time on your hands to get results close to what Reshade offers instantly.

2. Online Image Resizer

Why make available only fixed resolutions?

The resizing process takes time, so caching is needed. Fixed resolutions make this possible. Besides, you might not need other sizes. Most desktop resolutions are supported, and you can crop/stretch your pictures to change their aspect ratio (width/height).

Why not use other online resizers?

Reshade provides high quality resizing, which is not available in any other free online serice.

Can I crop pictures?

Reshade.com also offers cropping for your pictures. This means that you can test the zooming ability even more, and on larger images. Because of processing time concerns the maximum zoom factor is 300%.

Can I use Reshade to enhance my pictures?

Yes, reshade provides smoothing and denoising to improve the quality of old, pixelated, noisy pictures or images with compression artifacts.

3. Photo enlargement software

I saved my first image, but when I open it why is it not zoomed?

If this happens try opening the image at actual pixels/full size/100% zoom in your favourite image viewer. These programs try to fit the image to your screen by default, thus shrinking it. An enlarged image using the default settings is almost identical to the original when down-sized again.

What is the default compression level for Jpegs?

When saving in the JPEG format Reshade uses 95% compression. Please use BMP if you need a lossless format.

How come Reshade doesn't save the cropped image?

The rectangle on the right image pane represents the selected preview that will be displayed on the left. Reshade doesn't crop images. When saving, the full resized image is stored to disk. If you want to crop the image do this before resizing it with Reshade in your favorite image editor or using the online image resizer.

Can I make Reshade run faster?

With some settings there will be a significant delay in processing the image so the preview will not be refreshed instantly. A progress bar will be displayed at the buttom of the screen.
The time needed to save an image is greatly dependent on the settings used. The most time consuming options are zoom and edge control. The greater the values for these the longer it will take. Also, selecting “Best Edges" will double the delay.

What does the 150 megapixel limitation mean?

You will be able to resize images containing up to 150 million pixels (example: 20,000x7,500 pixels). This means you can enlarge photos taken with today's high-end digital cameras up to 10-20x magnification.

4. Image Gallery

Why do you show the zoomed image when my mouse if over a thumbnail?

When hovering the mouse over a thumnail a zoomed selection will be made showing the most detailed part of the larger image. Generally if this selection looks good the image is of better quality overall. This can make your browsing much simpler.

What do the terms of service say about copyright?

Reshade.com does not assume ownership of the works posted. The author allows reshade.com to resize his pictures, that's all. The resized pictures are still copyrighted to their author, so nobody can use them for any purposes not meant by the author. For example, this means that if an image has a Creative Commons Licence on it, this is transmitted to the resized image.

Can I submit pictures that are not mine?

You can submit any picture as long as you have permission from the author/owner to post it on reshade.com publicly. Please read the terms of service for more information. If you are not sure about a picture's copyright it's better to not submit. Pictures from magazines, commercial sites are usually copyrighted to their respective owners.

Why should I make an image public, if I can resize it while it's private?

First, the images you make public will have a link back to your site so that reshade visitors may see more of your pictures. Second, if anybody else submits any of the pictures on your site to reshade.com they will be redirected to the ones you've already submitted. This way you are properly given credit for your works.
