What do you need to get done?
Combine multiple Excel files into one
Keep worksheets separate or merge rows using the headers you choose. Works with XLSX, XLS, and CSV.
Crop multiple images to the same size
Set your output dimensions, adjust each photo's crop, and download the results together.
Make image files smaller
Resize photos or adjust JPEG and WebP quality, then compare the results before downloading.
Save PDF pages as JPG images
Turn pages into separate pictures and download them together in a ZIP file.
Format JSON and find errors
Paste messy JSON to make it readable. Inspect a collapsible tree and handle single-quoted input.
Combine CSV files into one spreadsheet
Choose which columns to keep, align their headers, and export the combined data as Excel.
