Image Compressor & Resizer
Upload your image to our main compressor tool, enter '20' in the Target KB field, and click Convert. Our algorithm automatically adjusts quality to achieve the exact file size while maintaining the best possible quality. The same process works for 50KB, 100KB, or any target size.
Use our main image resizer. Select 'cm' from the unit dropdown, enter your desired dimensions in centimeters, and the tool automatically calculates the required pixels at 300 DPI for print quality. You can also use mm, inches, or pixels.
DPI (Dots Per Inch) determines print quality. Screen images are 72 DPI, but printed photos require 300 DPI for sharp results. Our tools maintain 300 DPI minimum when you work in cm or mm, ensuring your photos look great when printed for exams, passports, or visas.
Check the "Maintain Aspect Ratio" box below the width/height inputs. When enabled, changing one dimension automatically adjusts the other to keep your image proportions correct, preventing stretching or distortion.
Passport Photo Maker
Indian passport photo requirements: Size 35x45 mm (2x2 inch equivalent), white background, face should occupy 70-80% of the photo, neutral expression, both eyes open, no glasses, no headgear (except religious). Use our Passport Photo Maker for perfect results.
US visa photo size is 2x2 inches (51x51 mm). Head height should be 1-1 3/8 inches (25-35 mm) from chin to crown. Background must be white or off-white. Our tool has a preset for US visa photos.
Yes! Our Passport Photo Maker lets you change background to white, light blue, light gray, or any custom color using the color picker. This is useful for different country requirements.
After creating your photo in the Passport Photo Maker, use the "Print Multiple Copies" section. Select paper size (4x6, A4, or 5x7) and gap between photos. Click "Generate Print Sheet" to download a ready-to-print page with multiple copies automatically arranged.
Signature Maker
Use our Signature Maker. You have three options:
- Draw: Use mouse or touch to draw your signature
- Type: Type your name and choose from various fonts
- Upload: Upload an existing signature image
Our Signature Maker includes professional fonts like Arial, Brush Script, Courier New, Georgia, Times New Roman, Verdana, Comic Sans, Trebuchet MS, Pacifico (handwritten), and Great Vibes (calligraphy).
PNG supports transparent background – ideal for overlaying on documents. JPG has white background and smaller file size. For most official uses, PNG is recommended as it looks professional without a white box around your signature.
PDF Converter
Use our PDF Converter. Select "Image to PDF" mode, upload your JPG files (you can add multiple), choose page size (A4, Letter, etc.), orientation, margin, and quality. Click "Convert to PDF" and download your PDF with all images combined.
Yes, select "Merge PDF" mode, upload your PDF files (they'll be merged in the order you add them), and click "Merge PDFs". Download your combined PDF instantly.
Select "PDF to Images" mode, upload your PDF, choose output format (JPG or PNG), quality, and DPI. Click "Extract Images" to get a ZIP file containing each page as a separate image.
Technical Issues
Common reasons:
- File format not supported (use JPG, PNG, or WEBP)
- File too large (try under 20MB)
- Browser compatibility (update to latest Chrome, Firefox, or Edge)
Yes! All ImResizer tools are fully responsive and work on smartphones and tablets. You can draw signatures with your finger, upload photos from your gallery, and download files directly to your device.
While there's no hard limit, very large files (over 50MB) may process slowly depending on your device's memory and processing power. For best performance, keep files under 20MB. If you need to process larger files, try reducing resolution first.
