How to Convert an Image Online Free in 3 Steps.
Step 1 - Upload Your Image
Click Upload or drag and drop your image file into the converter. Supported input formats: JPG, JPEG, PNG, WebP, SVG, BMP, ICO, HEIC, TIFF, GIF. The converter works in any browser (Chrome, Safari, Firefox, Edge) on any device including Android phone, iPhone, Windows PC, Mac, or Linux. For batch conversion, drag multiple image files at once.
Step 2 - Choose Your Output Format
Select your output format from the dropdown. The available output formats depend on your input: most formats convert to JPG, PNG, WebP, PDF, TIFF, and BMP. SVG output (for PNG and similar inputs) requires AI bitmap tracing. For format-specific guidance on which output to choose, see the format guide table in the next section.
Step 3 - Download Your Converted Image
Click Convert. Single files download immediately on completion. Batch conversions deliver a zip archive - click Download All, then extract. File names are preserved with the new extension (photo.heic → photo.jpg). All original uploads and converted outputs are permanently deleted from our servers within 60 minutes.
Which Image Format Should You Use? A Practical Guide.
The most common question after uploading an image is: which output format should I choose? The answer depends on what you intend to do with the converted image. Use this guide:
| Your Use Case | Best Format | Why |
|---|---|---|
| Portal upload (Aadhaar, NTA, IRCTC, Passport) | JPG | Accepted by all Indian government portals. Maximum 50-200KB typically. Convert any format to JPG first. |
| Website images - photographs | WebP (first choice), JPG (fallback) | WebP is 25-35% smaller than JPG. Modern browsers support WebP. Use JPG for email and older systems. |
| Logo or icon on a website | SVG (first choice), PNG (fallback) | SVG scales infinitely for any screen size. PNG preserves transparency for fixed-size logos. |
| Transparent background (logo, icon, cutout) | PNG | PNG supports full alpha channel transparency. JPG destroys transparency (white box). WebP also supports it. |
| Printing - standard documents | JPG at 300 DPI | JPG at 300 DPI is universally accepted by print shops. PDF for multi-page documents. |
| Printing - professional/archival | TIFF | Lossless compression, maximum print quality. Accepted by professional print software. |
| iPhone photos to share on WhatsApp/Windows | JPG | Convert HEIC to JPG. JPG opens on all devices and software. WhatsApp accepts JPG universally. |
| Browser favicon | ICO | ICO format is required for browser favicons. Standard sizes: 16×16, 32×32, 48×48 pixels. |
| Email attachment | JPG or PNG | Keep file size small. JPG for photos, PNG for screenshots and graphics with text. |
| App icons (Android/iOS) | PNG (various sizes) | PNG with transparency for app icons. Generate multiple sizes from one high-res PNG. |
Image Converter Features - Beyond Basic Format Conversion.
RepetiGo's image converter includes additional processing options that go beyond simple format re-encoding:
Black and White Image Conversion
Convert any colour image to greyscale in the same operation as format conversion. The black and white image converter option is available for all input formats and produces a greyscale output in your chosen format. Useful for: document scans that should be black and white for smaller file size, ID photos for specific portals that require black and white, artistic photography workflows, and reducing file size (greyscale images are smaller than colour at the same quality).
India use case: Aadhaar enrolment forms and some government applications require black and white passport photos. Convert HEIC to JPG with Black & White mode in one step.
DPI and Resolution Conversion
Change the DPI (dots per inch) setting of your image without resizing the pixel dimensions. The image dpi converter option lets you set the target DPI in the output file metadata: 72 DPI for web display, 150 DPI for basic office printing, 300 DPI for standard professional print quality, 600 DPI for high-end print reproduction. Note: DPI is a metadata tag in the image file - it tells printing software how large to print the image, but it does not add pixels that were not in the original. If you need higher actual resolution (more pixels), use the AI Upscaler tool.
HD and Image Enhancement
The standard converter delivers the output image at the same pixel dimensions and quality as the input. For upscaling low-resolution images - adding pixels to increase the actual resolution - use the AI Image Upscaler at Open AI Image Upscaler which uses neural network upscaling (2x or 4x). The image converter's DPI setting adjusts the print metadata only - for true HD upscaling, the dedicated tool is required.
Batch Image Conversion
Convert any number of images in a single operation. For batch image conversion: upload multiple files by dragging a folder selection or using Ctrl+Click (Windows) / Cmd+Click (Mac) in the file picker. Select your output format and any processing options - these are applied identically to all files. Click Convert All. All files process simultaneously. Click Download All to get a zip archive. File names are preserved with the new extension. No per-batch file count limit.
★ Indian Use Cases - Image Conversion in India.
Portal Compliance - Aadhaar, NTA, IRCTC Photo Requirements
Indian government and examination portals have strict image format requirements that the default camera app on many phones doesn't produce. iPhone users get HEIC. Chrome browser downloads arrive as WebP. Older cameras produce TIFF. None of these are accepted by Indian portals, which universally require JPG.
The image converter solves this in one step: upload any format, select JPG output, set file size appropriately (quality 75-85 usually brings file within 10-50KB portal limits), download portal-ready JPG. For further file size reduction after conversion, use the Open Compress Image tool. For background change to white (required for Aadhaar and NTA passport photos), use the Open Remove Background tool after conversion.
Common portal requirements: Aadhaar Update Portal requires JPG under 50KB. NTA (NEET/JEE/CUET) requires JPG between 10-50KB. IRCTC photo upload requires JPG under 50KB. Passport application requires JPG under 200KB. Digilocker accepts JPG and PNG. Bank KYC typically accepts JPG and PNG under 200KB.
Print Shops - Any Format to Print-Ready JPG
Print shops and cyber cafes across India receive customer files in every format imaginable - HEIC from iPhones, WebP from Chrome downloads, PNG from design files, BMP from legacy Windows software, TIFF from professional scanners, and GIF from old web assets. Every format needs to become a print-ready JPG before the job can proceed. The batch image converter handles the entire queue: upload all customer files regardless of format, convert the whole batch to JPG at 300 DPI in one operation, download the unified set, and proceed to print.
For print shops with automated customer upload workflows, PrintPilot - RepetiGo's automated print shop software - detects and converts any incoming image format to the required output format automatically, without manual intervention from the shop operator. Learn more at Explore PrintPilot.

Common Questions About Online Image Conversion.
Q1: What Image Formats Does RepetiGo Support?
RepetiGo's image converter supports the following input formats: JPG/JPEG, PNG, WebP, SVG (raster output), BMP, ICO, HEIC/HEIF (iPhone format), TIFF/TIF, GIF, and image-containing PDF pages. Supported output formats: JPG, PNG, WebP, BMP, ICO (favicon), TIFF, PDF, and SVG (for PNG and simple-colour inputs via AI tracing). For conversions involving complex format pairs - such as PNG to SVG (which requires AI bitmap tracing) or HEIC to JPG (which is the most common iPhone photo conversion) - dedicated specialist tools provide more settings and are linked at the bottom of this page.
Q2: How Do I Convert an Image for a Government Portal in India?
Step 1: upload your image (HEIC from iPhone, WebP from Chrome, PNG, BMP - any format). Step 2: select JPG as the output format. Step 3: set quality to 75-85 (this typically produces a file under 50KB which most Indian portals accept). Step 4: download the JPG. Step 5: check the file size - if it's still over the portal's limit, use the Open Compress Image tool to reduce it further. For photos requiring a white background (Aadhaar, NTA, passport), after converting to JPG, use the Open Remove Background tool to set the background to white.
Q3: What Is the Best Format for Each Use Case?
Short guide: Portal uploads (Aadhaar, NTA, IRCTC, Passport) → JPG. WhatsApp sharing → JPG (opens on all Android/iPhone/Windows). Website photos → WebP (smallest files for browsers). Website logos and icons → SVG (scalable) or PNG (with transparency). App icons → PNG. Browser favicon → ICO. Standard printing → JPG at 300 DPI. Professional/archival printing → TIFF (lossless). Transparent images for design work → PNG. iPhone camera photos for sharing → convert HEIC to JPG. See the format guide table above for more detail.
Q4: Can I Convert Multiple Images at Once?
Yes. Upload multiple image files at once by dragging a folder selection or using Ctrl+Click (Windows) / Cmd+Click (Mac) in the upload dialog. All selected files upload simultaneously. After uploading, select your output format and any processing options (quality, DPI, colour mode) - these are applied to all files in the batch. Click Convert All. All files process simultaneously regardless of count. Click Download All to get a zip archive of converted files. There is no per-batch file count limit. File names are preserved with the new extension. This batch image conversion feature is particularly useful for print shop operators converting mixed-format customer jobs to a unified JPG set.
