Photostr guides
Photo editing guides
Each guide covers one job from start to finish in Photostr, a free online Photoshop alternative that runs in your browser. They are short, and most include a sample file so you can practise before using your own photo.
Your first photo edit
Crop a photo, make an adjustment you can change later and add text, then decide whether to save a project or export a PNG or JPEG. Start here if you are new to layered editing.
Remove a background
Cut out a subject on your device, refine the edge with a mask and export a transparent PNG. The photo is not uploaded.
Open and edit a PSD online
View the layers in a PSD, change what you need and save it again as a layered file. Includes a two-layer practice PSD and a list of what to check before sending the file on.
Is Photoshop online free?
What is free from Adobe, and how to do the usual Photoshop jobs free in Photostr instead.
View a PSD online without uploading it
Look through the layers in a PSD and save a PNG or JPEG of it, with the file kept on your device.
Convert HEIC to JPG on your device
Turn iPhone HEIC photos into JPGs in your browser, one at a time or in a batch.
Remove an object from a photo
Brush over a person, sign or wire and let Photostr fill the gap, with tips for when the fill looks wrong.
Resize an image to exact pixels
Get an exact width and height without stretching the picture, and know when to crop or change the canvas.
Supported files and export formats
Which files Photostr opens, what stays editable in a PSD, and when to pick a project file, PNG, JPEG, TIFF, SVG or PDF.
