🖼️ Images to PDF 🗜️ Compress images 🧩 Stitch images

Images to PDF

Combine multiple images into one PDF, with one image per page. Supports PNG, JPG, WebP and BMP.

Choose images (multiple files allowed)

Up to 30 MB Click to select multiple images or drop them here PNG / JPG / WebP / BMP, up to 30 MB

Page size

Note: Original mode maps 1 pixel to 1 PDF point (1/72 inch), rather than deriving paper size from image DPI. A4 mode preserves source pixels, centers the image proportionally and does not enlarge small images. Transparent areas become white; EXIF orientation is corrected automatically.

📦 Image compression

Local compression with no image upload. Process images in batches and adjust quality and dimensions. Supports PNG, JPG, WebP and BMP.

Load the public test image with JPEG / 200 KB / no dimension limits. After compression, check the file size, pixel dimensions and small-text clarity.

Choose images (batch selection supported)

Up to 30 MB Click to select multiple images or drop them here PNG / JPG / WebP / BMP, processed locally with no server upload

Compression mode Quality: 80% Lower values usually make smaller files with lower image quality

Output format

Maximum width (px, 0 for unlimited)

Maximum height (px, 0 for unlimited)

💡 Note: All processing happens in your browser without uploading images. Setting maximum dimensions may further reduce file size.

🖼️ Image stitching (collage)

Drag, resize and arrange multiple images into one picture. Processed locally without uploading images.

💡 Controls: Drag to move · Drag corners to resize · Scroll to fine-tune size · Click to select · Press Delete to remove · After changing canvas dimensions, click"Apply"

First check whether the recipient needs an image or a PDF

File size, format and pixel dimensions are separate requirements. Reaching 200 KB does not ensure the correct format or dimensions. Renaming .png to .jpg does not change the image encoding.

Requirement	Tool to use	Check before downloading
A platform requires JPG, 200 KB and specific dimensions	Image compression → Upload requirements check	Check the actual format, bytes and pixel dimensions. Choose the KB definition stated by the receiving platform.
Combine scanned photos into a document	Images to PDF	Check image order, orientation and complete edges. Text in photos does not automatically become searchable.
Arrange screenshots in one image	Image stitching	Adjust position, scale and layers on a freeform canvas. Check overlaps, gaps and content outside the canvas.

Example: a photo under 200 KB is still rejected

Record all platform requirements: allowed formats, maximum size, exact dimensions, aspect ratio and background requirements.
Use the Upload requirements check to read the file. Blank conditions are marked as needing confirmation, rather than automatically passing.
If only the size is too large, try compression. If dimensions are wrong, adjust and recheck them without stretching faces or documents.
Zoom in to check text and facial details before submitting. This site checks file properties, not people, backgrounds or business review requirements.

How do quality, dimensions and format affect the result?

Reducing pixel dimensions removes detail. Lowering JPEG quality can introduce blur and blocks. PNG size may not follow the quality slider; converting to JPEG removes transparency. Recheck the downloaded result instead of relying only on settings.

Does passing this check guarantee upload acceptance?

No. A platform may check content, background, validity dates or other unpublished conditions. This site checks only the file properties you enter. Follow the receiving platform error message if it rejects a file.

Do compression and stitching upload my images?

Both run locally in your browser. Images to PDF uploads files for temporary server processing. Large images or canvases can exceed device memory; reduce the image count or output dimensions if processing fails.

How can I keep compressed images readable?

Keep the original and start each adjustment from it. Check small text, edges and gradients. If the target size cannot preserve readability, ask the recipient whether another format or multiple submissions are acceptable.
