How to Upload Your Files

Short Summary

Upload your artwork while setting up a print order. You can upload without an account, then choose the size and options for each image and review the crop before adding it to your cart.

Quick Answer

Choose a print product on thestackhouse.com, then select Upload images in the order builder. You can choose up to 10 files at once. JPEG, PNG, and TIFF are supported, with a 1 GB limit per file. After upload, select an image and follow the steps for size, crop, media, and any available options. Review the preview before adding the configured print to your cart.

Before You Begin

• Keep your original file and prepare a JPEG, PNG, or TIFF in RGB color mode. An embedded color profile is helpful when available. See How to Prepare Your Image Files for Printing.
• Each file must be no larger than 1 GB, 324 megapixels, or 18,000 pixels on either side.
• Use a stable internet connection, especially for large TIFF files. Give the upload time to finish before moving to the next step.

How It Works

Step 1: Choose a print product

Open the product you want to order on thestackhouse.com and start the order builder. The current builder begins with an Image step. If you use the classic builder, its file selector is labeled Browse files.

Step 2: Upload your artwork

Select Upload images and choose files from your computer or device. You can select up to 10 at once in the current builder. Wait for the upload to complete, then choose the image you want to configure. In the classic builder, select Browse files to upload.

Step 3: Choose the print settings

Follow the builder to choose the size and crop, media, border, and any other options available for your product. Set up each image you want to print with its own choices.

Step 4: Review the preview

Check that the important parts of your image are inside the print area. If the crop or size does not look right, adjust it before adding the print to your cart.

Step 5: Add to cart

Add the configured print to your cart. If you are printing more images, configure each one and add it to your cart before checkout.

Important Notes

• You do not need an account to upload artwork. Guests and signed-in customers have the same supported upload options. Sign in if you want to use images saved in your account Library.
• Supported layered RGB TIFF files can be prepared from their saved combined image. Your original file stays unchanged. Review the resulting preview before ordering.
• Selecting several files uploads them together; each print still needs its own size, crop, and product choices.
• If a file fails to upload, check its format, size, dimensions, color mode, and connection. See Common Image Upload Issues and How to Fix Them.
• If the image is too small for the print size you chose, select a smaller size or upload a higher resolution file.

Examples

One image, one print

Upload the image, select its size and options, review the crop, and add the print to your cart.

Three images, three prints

Choose the three files together in the current builder. After they upload, configure each image and add each print to your cart.
