Which image format should you use?
Most “which tool do I need” questions come down to the file format. Here is what each common format is good at, and when to switch to another one.
| Format | Best for | Watch out for |
|---|---|---|
| JPG | Photos you want to email, upload to a form or print. Opens on every device and website. | Lossy: each re-save at low quality loses a little detail. No transparent backgrounds. |
| PNG | Screenshots, logos, diagrams and anything with sharp text or a transparent background. Lossless. | Photos saved as PNG are often 5–10 times bigger than the same photo as JPG. |
| WebP | Images for websites: usually smaller than JPG at similar quality, and supports transparency. | Some older apps, editors and upload forms still do not accept it. |
| HEIC | What iPhones save by default. Good quality in a small file. | Many Windows programs, websites and Android apps cannot open it, so it often needs converting. |
| Sending several pages as one file: applications, receipts, scanned documents, contracts. | Not an image format for editing. To reuse a page as a picture, convert it back to JPG or PNG. |
If you are unsure, JPG is the safe default for photos and PNG for screenshots. The image converter switches between JPG, PNG and WebP in a few seconds.
Common jobs and the tool for each
- A photo is too big to email or upload. Use Compress Image and pick a target such as 200 KB or 500 KB. It lowers the JPG quality step by step and only shrinks the dimensions if quality alone is not enough.
- A website asks for exact pixel dimensions, such as 1080×1080 for a profile picture or 1200×630 for a link preview. Use Resize Image with “Crop to fill” to get exactly that size.
- Photos from an iPhone will not open on a PC or upload to a form. They are probably HEIC files. Convert them with HEIC to JPG, or HEIC to PNG if you want no further compression.
- You need to hand in several pictures as one document. Put them in order and create a single file with Image to PDF, JPG to PDF or PNG to PDF.
- You have several PDFs that belong together, like a form and its attachments. Combine them with Merge PDF.
- You need one page of a PDF as a picture, for a slide or a social post. PDF to JPG and PDF to PNG turn every page into an image at up to 300 dpi.
- A downloaded image is WebP and your app will not take it. Use WebP to JPG, or WebP to PNG to keep a transparent background.
- You need a product or portrait without its background, or on plain white. Background Remover cuts out the subject and saves a transparent PNG or puts it on a colour you choose.
- A logo or icon looks blurry when you enlarge it. PNG to SVG traces it into vector paths that stay sharp at any size.
- A video is too big to send or upload. Compress Video re-encodes it to a size you choose in MB. To share just a few seconds as a looping picture, make a GIF with Video to GIF.
- An iPhone video will not play on a Windows PC, or you only want its sound. Use MOV to MP4, or MP4 to MP3 to keep just the audio.
- An API or app gave you a JSON file and you need a spreadsheet. JSON to CSV turns it into CSV or Excel, with nested fields as columns.
How the tools work without uploading your files
Most online converters send your file to a server, process it there and send the result back. Capypix does the work inside the browser tab instead. Modern browsers can decode images, draw them onto a canvas at a new size and save them again as JPG, PNG or WebP, all on your own phone or computer. PDF files are built and read with open-source libraries that run in the same tab, video is decoded and re-encoded with the codecs built into your browser, and background removal runs a small AI model on your own graphics card or processor.
This has a few practical consequences. Your photos are never sent anywhere, so there is no upload wait and nothing is stored on a server. Speed depends on your device rather than your connection, and large batches run one file after another. Some tools need extra code the first time you use them — the HEIC decoder, the PDF and video engines are loaded only when needed, which takes a few seconds on a slow connection, and then they are cached by the browser. The background remover’s AI model is the big one, about 97 MB, so the tool tells you before it starts downloading.
There are limits, too. Very large batches or very large images use a lot of memory, and phones have less of it than computers; if a tab struggles, convert in smaller groups. Converting or compressing re-saves the image, so the result does not keep metadata such as the camera model or GPS location. Keep your original files until you have checked the results.
Frequently asked questions
Is Capypix really free?
Yes. There is no sign-up, no watermark and no daily limit. To cover running costs the site may show a small number of ads, kept away from the file picker and download buttons.
Are my files uploaded anywhere?
No. Every tool runs in your browser on your own device. Files are read from your device, processed in the page and saved back to your downloads. We have no server that receives them.
Does it work on iPhone and Android?
Yes. Open the site in Safari, Chrome or another modern browser and choose files from your photos or files app. One exception: some versions of Safari cannot create WebP files, so choose JPG or PNG there.
Is there a file size or number limit?
There is no fixed limit. The practical limit is your device’s memory: dozens of photos at once work fine on a normal phone or computer, while very large batches are better done in a few rounds.
Will converting reduce quality?
Converting to PNG keeps every pixel. JPG and WebP are compressed; at the default settings the difference is hard to see. Avoid saving the same JPG again and again at low quality, and keep your originals.
