Choose Compress, Resize, Crop, Convert, Add watermark, AI watermark removal, AI background removal, or AI upscaling from the operation rail.

Select Add images for specific files, Add folders to discover supported files inside a folder, or drag files directly into the window.

Wait until each row has finished reading its format, dimensions, size, and status. Options stay locked while files are still being prepared.

Remove unwanted rows or use Clear to start over. Reset options restores the current tool's defaults without removing files.

Choose Compress and add supported images or, with an activated license, PDF files.

Review the format groups shown in the options panel. A mixed batch can expose several groups at once.

Set the desired clarity, color, effort, or compression options. Start near the defaults, then lower clarity gradually when size matters more.

Run Compress. Compare the original and processed size in each row, preview visual changes where available, and save the accepted results.

Choose Resize and add images.

Select a resize method: width, height, short edge, long edge, ratio, or exact width and height.

Enter integer dimensions from 1 to 100,000. Enable Shrink only when small originals must never be enlarged.

Run Resize, inspect the processed dimensions in the list, and use Preview to check sharpness and geometry before saving.

Choose Crop and add images.

Select By width and height for a fixed pixel crop, or By ratio for a proportional crop.

For ratio crops, choose 1:1, 4:3, 3:2, 16:9, 9:16, or enter a custom width and height ratio.

Choose one of nine anchors to decide which part of the image remains, run Crop, and verify the composition in Preview.

Choose Convert, add images, then select JPEG, JPG, PNG, GIF, WebP, AVIF, HEIC, HEIF, TIFF, TIF, BMP, SVG, JP2, J2K, JXL, or PDF.

Set options shown for the selected destination: clarity, compression level, colors, dithering, effort, lossless mode, or TIFF compression.

Read the animation notice before processing. Still formats keep only the first frame of animated input; converting a still image to GIF or WebP does not create animation.

Run Convert and confirm the new format and size in the list before saving.

Choose Add watermark and select Text watermark or Image watermark.

For text, enter the wording, system font, and color. For an image mark, choose a local logo or graphic.

Choose One watermark or Repeat across image. A single mark can be placed at a corner or in the center.

Tune opacity and size; for tiled marks, adjust spacing. Process and preview the mark on light and dark parts of the image before saving the batch.

Choose AI background removal and add images with a clearly distinguishable subject.

Choose Transparent for reusable cutouts or Solid color for a finished background, then select the color if needed.

Choose Standard for faster batches or High when hair, fine edges, and small details matter more than processing time.

On first use, approve the required model download. After it is stored locally, processing can run offline. Process and inspect edges in Preview.

Choose AI watermark removal and add authorized images.

Select Standard for faster batches or Detailed to detect smaller watermark edges.

Start with Balanced cleanup. Use Conservative to protect nearby detail or Strong when faint edges remain.

Download the two required model resources on first use, process the images, and inspect every repaired region at a useful zoom before saving.

Choose AI image upscaling and add the source images.

Choose 2× for a moderate size increase or 4× when substantially more output resolution is required.

Use Standard for general work or Detailed when fine texture matters and extra processing time is acceptable.

Approve the first-use model download, process, then inspect the result at 100% rather than judging only from a fit-to-window view.

After processing, choose Preview on a completed row to open the original and processed result on one aligned canvas.

Use the shared zoom controls or the mouse wheel. Above the fit level, drag either side to pan both views together.

Use Save as for one item or Save all as to choose a destination folder for every completed result.

Choose overwrite only when you intentionally want to replace source files. Confirm the warning and keep a backup for irreplaceable originals.

Open Settings from the title area.

Enable Keep working from the last result when the next operation should consume the previous output. Leave it off when every tool should start from the untouched original.

Enable Save last operation settings to restore the active tool and its parameter values in future sessions.

Choose a temporary folder with sufficient free space. Save settings, then process and switch tools to build the desired chain.

Select the license status in the application and enter the activation code exactly as issued.

Stay online while the device is activated. After success, open the license status again to review activation time, expiry or lifetime status, and active devices.

Continue normal local work offline. Reconnect periodically so the application can refresh its signed authorization when needed.

If the device was released and later restored by an administrator, reconnect and select the license status. PicSmaller attempts recovery before showing activation again.
