Convert, Resize, and Compress Images in Batches

GiliSoft Image Converter prepares phone photos, camera files, product images, screenshots, and scanned pictures for everyday use. Convert common formats including JPG, PNG, WebP, BMP, GIF, and TIFF, or open the dedicated HEIC and RAW conversion tools to make phone and camera sources easier to share and use on Windows.

Make an image set consistent without adjusting every file by hand. Batch Resize provides custom width and height, Keep Aspect, Stretch Mode, and size presets. Batch Rename lets you set a name prefix, starting number, and interval, with the new names shown before processing. Separate tools handle cropping, rotation, compression, and classification.

Convert scans and pictures to PDF, split an image into smaller pieces, or merge images for a combined visual. The task launcher also offers Image to Scanned, an image editor, enhancement tools, and photo repair utilities when your project needs more than conversion.

Choose the task, add the images, set the available output options, and save to a new folder. Run additional batch tools as needed and review a sample before processing the full set. The Image Converter user guide shows the real workspaces and output checks. Download the free trial to evaluate the tools with your own images.

Image Converter Features

Convert Common Image Formats

Use Common Conversion for JPG, PNG, WebP, BMP, GIF, TIFF, and other supported images. Add multiple files, choose the available output format, and prepare copies for sharing or publishing.

Convert HEIC and RAW Sources

Open HEIC Conversion or RAW Conversion for supported phone and camera sources. Create JPG or PNG copies for review, uploads, design projects, and everyday Windows applications.

Resize Photos with Aspect Controls

Enter a custom width and height or choose a size preset in Batch Resize. Use Keep Aspect to retain proportions, compare the preview, and apply the settings to the intended set.

Compress Images for Smaller Files

Use Image Compression to prepare lighter copies for websites, email, documents, and storage. Compare fine detail and file size on a sample before processing the full collection.

Convert Pictures to PDF

Open Image To PDF and convert supported pictures, scans, and screenshots to PDF output. Choose an output folder and review the finished files before sending or printing them.

Batch Crop and Rotate Images

Use Batch Crop to reframe an image set or Batch Rotation to correct orientation. Review the subject and boundaries when the source images have different sizes or compositions.

Rename Photos with Number Sequences

Set Name Prefix, Start Num, and Intervals Num in Batch Rename. Check the New Name column before creating a consistently named catalog, project folder, or image archive.

Split and Merge Images

Choose Split Image to divide one picture into smaller pieces, or Merge Images to combine selected pictures into one visual. Prepare the layout in the dedicated tool.

Organize Images with Batch Classification

Open Batch Classification to group an image set using the options provided by the tool. Keep a separate working copy when preparing a large photo collection.

Create a Scanned-Image Appearance

Choose Image to Scanned when a picture needs a scan-style visual treatment. Preview the result for documents, project materials, and presentation images.

Convert an Image Batch in Three Steps

Choose the task you need, add the image set, and review a finished sample before processing the rest.

1

Choose a Tool and Add Files

Open Common Conversion, HEIC Conversion, RAW Conversion, or a batch tool. Click Add Files or drag supported images into that workspace.

2

Set the Output for That Task

Choose the target format in conversion, dimensions in Batch Resize, or a name sequence in Batch Rename. Set a separate output folder.

3

Convert and Check the Result

Click Convert, open a saved sample, and check its appearance, dimensions, file size, and name. Continue with another batch tool if the project needs more preparation.

Choose an Image Format for the Job

JPG for Everyday Photos

Prepare phone and camera pictures for sharing, email, and applications that expect JPG. Balance compression and dimensions against visible detail.

PNG for Graphics and Transparency

Use PNG for screenshots, sharp text, and images that need a transparent background. A format change alone does not cut out an existing background.

WebP for Web Images

Choose WebP when the destination website or publishing system accepts it. Review the saved image and file size rather than assuming every conversion will be smaller.

Built for Everyday Image Work

Prepare product images for listings

Prepare a consistent catalog with the conversion, resize, crop, and rename tools. Use Keep Aspect for product proportions and a clear file-name sequence for your listings.

Convert phone and camera sources

Use HEIC Conversion for phone photos and RAW Conversion for supported camera files. Create JPG or PNG copies for customers, colleagues, design applications, and photo sharing.

Reduce web image dimensions and size

Create lighter delivery copies for article images, support screenshots, campaign assets, and documentation while retaining the original files.

Convert scans and proofs to PDF

Use Image To PDF for supported scans, screenshots, visual records, and review proofs. Inspect readability and orientation in the resulting PDFs before sending or printing.

Editing, Enhancement, and Photo Repair Tools

Simple image editing

Open Image Edit for the image editor, Resize Image, Crop Image, Rotate Image, and Rename Image. Prepare an individual picture before creating the delivery copy.

Beauty enhancement

Explore Image Beauty tools for face repair, sky replacement, colorization, image enhancement, watermarks, and image matting from the same task launcher.

Old and damaged photo repair

Choose Old Photo Repair to improve a faded image, or Fix Corrupted Image when a damaged file needs repair. These are separate tools in the Image Repair category.

Image recovery

Open the recovery utility when images were deleted or lost. Recovery is a separate task from converting healthy source files.

GiliSoft Image Converter FAQ

Is GiliSoft Image Converter free?

GiliSoft Image Converter provides a free trial, with paid licenses available for the full product. Try representative source files and the tools you need before choosing a license. Check the trial and activation screens for the restrictions that apply to the installed build.

Can I convert HEIC and RAW images to JPG or PNG?

Yes. Use HEIC Conversion or RAW Conversion for supported phone and camera sources, then choose an available output such as JPG or PNG. JPG is useful for everyday photo sharing; PNG is useful for lossless image output. Test a sample from the phone or camera that produced the files before converting the full set.

Can I convert multiple images and run other batch tasks?

Yes. Use Add Files or drag multiple supported images into the selected workspace. Format conversion, resizing, cropping, rotation, renaming, compression, and classification have dedicated tools. Run the required tasks in sequence when the same image set needs more than one type of preparation.

How do I resize photos without stretching them?

Open Batch Resize, add the photos, and choose Keep Aspect rather than Stretch Mode when the original proportions should remain unchanged. Review the output width and height, use Apply To All for the intended image set, choose an output folder, and inspect the converted results.

Can I rename photos with a prefix and number sequence?

Yes. Open Batch Rename and add the image set. Set Name Prefix, Start Num, and Intervals Num, then review the New Name column before running the task. Use a separate output folder so the original names and files remain available.

Will converting or compressing images reduce quality?

The result depends on the output format, compression settings, and dimensions. JPG uses lossy compression, while PNG supports lossless image storage. Smaller dimensions remove image detail, and converting a low-quality source cannot recreate missing detail. Save a test copy and compare text, edges, gradients, colors, and file size at full view.

Can I convert JPG, PNG, or other pictures to PDF?

Yes. Open Image To PDF, add supported images such as JPG or PNG, choose the output folder, and run the conversion. Open the resulting PDF output to check the image orientation, readability, and dimensions before sending or printing it.

How do I keep a transparent background when converting images?

Choose an output that supports transparency, such as PNG, and inspect the saved file in the application where it will be used. JPG does not support transparent backgrounds. Converting a JPG to PNG changes its file format but does not automatically remove the existing background.
